 Title    Light and D ark Adaptation of Crayfish Visual Cells Depending on Extracellular Calcium Concentration  
 Abstract    Lowering of extracellular Ca2+-concentration from 14 x 10-3 M to ca. 10~ 6 M (using 1 mM ethyleneglycol bis (/?-aminoethylether) -N,N'-tetraacetic acid (E G T A)) results in weaker light adap­ tation by a 2 s light exposure and faster dark adaptation (half time 45 + 1%) of crayfish visual cells.

 Title    Effect of Isobutylmethylxanthine and Related Drugs on the Receptor Response (ERG; a-Wave) of the Frog Retina at Various Extracellular Calcium Concentrations  
 Abstract    Various drugs known or expected to increase the levels o f cyclic nucleotides in cells were applied to isolated superfused frog retinae, and their influence on the aspartate-isolated a-wave was studied. Isobutylmethylxanthine (IBMX), triacetylguanosine (TAG), and dimethylaminopurine (DAMP) strongly influenced the responses elicited from dark-adapted retinae by flashes o f light With all three drugs the response amplitude was increased, and latency and time to peak were prolonged. If, on the other hand, the retinae were light-adapted by background light o f various intensities, the drugs showed different effects on the response amplitude: IBMX either did not influence the amplitude at all or even caused a decrease (4 o f 6 experiments), DAMP decreased the amplitude and TAG caused an increase of the amplitude in 2 o f 3 experiments. But latency and time to peak were still prolonged by all three drugs. When dark-adapted retinae were superfused with IBMX or TAG Ringer solution and simul­ taneously calcium concentration was raised, different effects o f calcium on the three measured parameters of the a-wave were observed: By increasing the extracellular calcium concentration the increase of the amplitude caused by the drugs was reversed, down or even below the control level, whereas latency and time to peak remained prolonged. Thus, both an increased calcium level and light adaptation had the same effect, namely to reverse only that part o f the drug effect concerning the amplitude but not latency or time to peak o f the response. The data suggest that calcium and cyclic nucleotides act through different ways in the rod cells.

 Title    Isotopieeffekte in der Grenzschicht anorganischer Lösungen Isotope Effects at the Surface o f Inorganic Solutions  
 Abstract    Isotope effects were investigated at the surface of aqueous lithium and calcium salt solutions. The dependence on the temperature in the gas phase was determined. The surfaces of the solutions were isolated by spray experiments. In the case of calcium salt solutions an enrichment of the lighter isotope 40Ca in relation to the heavier isotopes 44Ca and 48Ca was found at the solution surface. The experiments with lithium fluoride and lithium iodide gave inverse isotope effects. The calcium isotope effect could be qualitatively explained by the Gibbs theorem. The isotope separation of lithium possibly can be referred to the more covalent bonding character than the ionic one of lithium compounds at the solution surface.

 Title    Ein Beitrag zur Kristallchemie dreiwertiger Seltenerdoxide Zur Stabilisierung der m onoklinen B-Form  
 Abstract    Single crystals of 1 — a'Ho203 : xCaO (x = 0.07), CaHoC>2.5 (A) and Cao.5H 01.5O2.75 (B) were prepared by high temperature reaction and investigated with X-ray single crystal data. It can be shown that small amounts of CaO stabilize the monoclinic B-Typ of rare earth oxides. Phase (A) and (B) cannot be seen as a stabilized B-type crystal because they have an new crystal structure with space group C.7h-P 2 i/m, a = 656.6, b = 356.7, c = 529.4pm , ß = 92.3°; a = 650.2, b = 352.4, c = 584.5, ß = 92.3°.

 Title    Abhängigkeit der Calcium-Isotopenseparation bei der Ionenaustauschchromatographie von der HN03-Elutionsmittelkonzentration Calcium Isotope Separation by Ion Exchange Chromatography in Dependence on the HNO3 Eluant Concentration  
 Abstract    Using a strongly acidic cation exchanger resin, the dependence of the calcium isotope separation on the HNO3 eluant concentration is investi-gated on column experiments. The elementary separation effect of the isotope ratios 44 Ca/ 40 Ca and 48 Ca/ 40 Ca is determined. Up to HN03 concentrations of about 1.5 M the lighter calcium isotopes are enriched in the resin phase, whereas, using more concentrated HN03 solutions, the heavier isotopes are enriched in the ion ex-changer. A comparison of these results with those using hydrochloric acid and perchloric acid show, that there is a strong dependence of the isotope separation on the concentration and the counter ion of the eluant solution.

 Title    Ternäre Gamma-Messing Phasen in den Systemen Calcium-M IB(IIB) -Quecksilber New Ternary Gamma-Brass Phases in the Systems Ca-M iB(nB)_Hg  
 Abstract    A series of new ternary intermetallic com-pounds of the general composition CaißMi8IB(IlB)_Hg18 (M = Zn, Cd, Hg, Cu, Ag and Au) has been identified. The X-ray powder diffraction patterns were indexed on a basis of primitive cubic unit cells. From the X-ray data and density measure-ments it is concluded that these phases belong to the partially disordered (Ml B (HB) and Hg) gamma-brass structure type D83.

 Title    Calciumisotopenseparation mit Kryptanden als Komplexbildner Separation of Calcium Isotopes with Cryptand Complexes  
 Abstract    The calcium isotope separation in the liquid-liquid extraction system H2O/CHCI3 is investigated using [2.2.1] and [2.2.2] cryptands for complex formation as well as without complexing agent. An extraction procedure is used which allows the transfer of larger amounts of calcium into the CHCI3 phase although the high distribution coefficient favours calcium in the H2O phase. Without complexing agent in the extraction system, enrichment of the lighter calcium isotopes is already evident in the CHCI3 phase which is just the same as when using [2.2.1] cryptand. In the case of [2.2.2] cryptand as a com-plexing agent, the isotope separation is higher. The separation factor is calculated to be a = 1 + e = 1.011 for 40 Ca/ 48 Ca without complexing agent or with [2.2.1] cryptand and a = 1.015 in the system with [2.2.2] cryptand. For 40 Ca/ 44 Ca the e-value is smaller by nearly a factor of two. These separation factors are the highest which are determined in chemical systems for calcium isotopes.

 Title    Inversion der Calcium-Isotopenseparation an einem Ionenaustauscher durch Ver- änderung der LiCl-Elektrolytkonzentration Inversion of the Calcium Isotope Separation at an Ion Exchanger Resin by Variation of the LiCl Electrolyte Concentration  
 Abstract    The calcium isotope separation at a strongly acidic exchanger resin as a function of the concentration of a LiCl solution is investigated in column experiments. Whereas an enrichment of the heavier calcium isotopes in the solution phase is found with a 3 M LiCl solution, an inverse effect is obtained with 8 M and 12 M LiCl solutions. The separation effect e for the 12 M solution is found to be the highest calcium enrichment in a system without a complexing agent. The results are compared with those for other electrolyte solutions and can be explained by the anion/cation interactions.

 Title    Hydroxy Complexes of Gold 2. Calcium Aurates [1]  
 Abstract    Two calcium aurate phases have been obtained as single crystals, phase 1 from H AUC1 4 + Ca(OH) 2 and phase 2 from NaAu(OH) 4 + Ca(C10 4) 2 . An X-ray structure determination of 1 shows its composition to be Ca 2 (0H) 3 (H 2 0) 4 [Au(0H) 4 ]. The apparent space group is Cmcm, but this corresponds to a sub-cell of the true structure. The disordered Cmcm structure was refined to R 0.032 for 813 reflections. The coordination geometry is square planar at gold (Au-O 1.97, 1.99 Ä), cubic at Ca(l) and octahedral at Ca(2). Phase 2 crystallizes in a primitive tetragonal cell with a 6.94, c 7.71 Ä; it is probably Ca[Au(OH) 4 ] 2 , but this has not yet been confirmed by a full structure determination.

 Abstract    Calcium-and strontium bis[bis(trimethylsilyl)amide] react with bis(trimethylsilyl)arsane in tetrahydrofuran to give the corresponding tetrakis(tetrahydrofuran-O) metal bis[bis(trime-thylsilyl)arsanides]. The calcium derivative crystallizes in the triclinic space group P I with a = 1191.7(2), b = 1232.0(2), c = 1655.0(2) pm, a = 102.46(1)°, ß = 107.92(1)°, y = 104.66(1)° and Z = 2, the strontium derivative in the orthorhombic space group Pbca with a = 2153.4(3), b = 1852.2(3), c -2182.4(3) pm and Z = 8. Both m olecules exist as frans-isomers with a nearly linear A s -M -A s moiety; however, the strontium analogue contains two remarkably different configurations for the arsenic atoms. One A s atom is surrounded nearly trigonally planar with a S r -A s bond length of 310 pm, whereas the other pnictogen atom has an angle sum of 338° with a S r -A s distance of 315 pm.

 Abstract    Single crystals of Ba(Ca<).6Mn0 4)V20 7 have been prepared by crystallization from melts. X-ray investigations revealed a new quaternary vanadium oxide of the type BaMV20 7. The M positions are occupied statistically by Ca2+ and Mn2+. The compound crystallizes wi|h orthorhombic symmetry, space group D^-Pnma, a = 15.429(2), b -5.7005(12), c = 7.364(2) A, Z = 4. The crystal structure can be interpreted as a [Ba(Ca,Mn)06] network with incorporated V-O-V groups. Considering the nearest O2-neighbours of the incorporated vanadium, the V-O-V groups are complemented to give V20 7 divanadate units. Ba(Ca« 6Mn0 4)V20 7 is isotypic to BaMV20 7 (M=Ca,Cd) but not to BaMnV20 7.

 Title    Kurze O-O-Abstände einer gemeinsamen Polyederkante bei Verknüpfung von P 0 4-Tetraedern mit V 0 6-0ktaedern im Vanadyl-Orthophosphat C aN i(V 0)(P04)2 Short 0 -0 Distances in Edge Sharing P 0 4 Tetrahedra and V 0 6 Octahedra o f the Vanadyl- Orthophosphate C a N i(V 0 )(P 0 4)2  
 Abstract    Single crystals of the new compound C aN i(V 0)(P 04)2 have been prepared by solid state reactions below the melting point of the oxide mixture in evacuated quartz tubes. X-ray inve­ stigations ledoto orthorhom bic symmetry, space group D2£-Pnma, a -14.113(1), b -6.408(1), c = 7.364(1) A, Z = 4. The crystal structure shows J. [N i0 4] and J. [V 0 6P20 3] polyhedra chains closely related to analogous chains in the isotypic compound CdV20 (P 0 4)2. The short V -0 distance of 1.66 A indicates a vanadyl group as the main difference to CdV20 (P 0 4)2. The short 0 -0 distance of 2,395 A of the edge-sharing P 0 4 tetrahedra and V 0 6 octahedra is discussed.
