	Title	Zur Kenntnis farbiger ternärer und quaternärer Zintl-Phasen Coloured Ternary and Quaternary Zintl-Phases
	Abstract	Ternary and quaternary, mostly coloured compounds of Au, Pd and Pt, resp., with Li, Mg, Sc and Sn were prepared and structurally investigated. They crystallize in a "filled" Zinkblende type structure (space group F?3m) and can be characterized as ternary or quaternary Zintl-phases. Colours seem to depend on unfilled d-orbitals of Au, Pd or Pt.

	Title	New Magnesium Compounds /fcE2Cu2Mg (RE = Y, La -Nd, Sm, Gd -Tm, Lu) with Mo2FeB2 Type Structure
	Abstract	The title compounds were synthesized by reaction of the elements in sealed tantalum tubes in a water-cooled sample chamber in a high-frequency furnace. These magnesium intermetallics crystallize with the tetragonal Mo2FeB2 type structure, space group PMmbm. The lattice pa rameters of all compounds were refined from X-ray powder data. Single crystal X-ray data yielded a = 792.09(6), c = 396.31(8) pm, wR2 = 0.0396, 315 F 2 values for La2Cu2Mg, a = 778.30(5), c = 384.04(5) pm, wR2 = 0.0954, 214 F 2 values for Nd2Cu2Mg, and a = 762.65(5), c = 374.09(3) pm, wR2 = 0.0566, 186 F 2 values for Y2Cu2Mg with 12 variable parameters for each refinement. The /?£, 2Cu2Mg structures can be described as an intergrowth of distorted A1B2 and CsCl related slabs of compositions RECui and REMg. Chemical bonding in La2Cu2Mg was investigated on the basis of extended Hückel calculations and compared to isotypic La2Cu2ln. This structure was also refined from single crystal X-ray data: PMmbm, a = 780.8(2), c = 400.1(2) pm, wR2 = 0.0351, 211 F 2 values and 12 variable parameters.

	Abstract	A series of magnesium inner complexes has been prepared by reacting M gH2 (prepared by homogeneous catalysis) with dialkylallyl-and -3-butenylam ines and -3-butenylethers in the p re sence of catalytic amounts of Z rC l4. The m onom eric nature of bis(4-m ethoxybutyl)m agnesium has been confirmed by X-ray diffraction. The analogous syntheses of bis(3-alkoxypropyl)magnesium com pounds failed: cleavage of the allyl ether with elimination of propene occurred. This cleavage reaction is accelerated by catalytic amounts of NiCl2 or ZrC l4.

The orange (I) and dark red (II) crystals show monoclinic symmetry, space group C2h -P2,/c, (I): a = 6.167(3), b = 8.172(5), c = 6.400(8) Ä, ß = 116.22(3)°, Z = 2; (II): a = 6.453(1), b = 8.342(2), c = 11.517(2) Ä, ß = 90.44(2), Z = 4. Both compounds show ordered metal distributions and vanadium in tetrahedral coordination by oxygen. (I) is characterized by elongated C u06 octahedra and (II) by trigonal C u 0 5 bipyramids. ra-Mg2CuV20 8 is the low temperature form of the formerly investigated orthorhombic o-Mg2CuV2Ö8.

	Title	Kristallstruktur von MgS03*H20
	Abstract	The crystal structure of M g S 0 3 H20 , space group P 2 \ln, Z = 4, Dx = 2.415 g em -3 , a = 4.699(1), b = 12.751(3), c = 5.618(1) Ä, ß = 90.49(3)°, was determined by single crystal X-ray diffraction. M g S 0 3 H20 crystallizes in the M n S 0 3 H20 type. The structure consists of buckled trans layers ^ [M gS03 H20 ], which are built up from strongly distorted M g 0 5(H20) octahedra sharing four equatorial vertices, and of trigonal pyramidal S 0 32-ions. It is close ly related to the structures of orthorhombic M nSe0s3 D 20 and monoclinic Z n S e 0 3 H20 . The M g -0 distances range from 2.051(3) to 2.175(4) A. The S-O distances (1.543(3), 1.547(3) and 1.493(3) Ä) and the O-S-O angles (98.4(2) and 2x 106.0(2)°) correspond to those in M n S 0 3 H20 . The distortion of the M 0 5(H20) octahedra (M = Mg, Mn) and of the S 0 32-ions is smaller in M g S 0 3 H20 , but with greater deviations from m symmetry. The distances between the H-connected ^ [M S 03 H20 ] layers are greater in M g S 0 3 H 20 , indicating weaker inter-layer hydrogen bonds. The lateral arrangement of the 2 [M S 0 3 H20 ] layers is nearly the same in both sulfite monohydrates. E in le itu n g

	Title	Effect of Divalent Cations on Cation Fluxes Across the Chloroplast Envelope and on Photosynthesis of Intact Chloroplasts
	Abstract	The effect of divalent cations on cation fluxes across the chloroplast envelope and on photo synthetic reactions of intact spinach chloroplasts was investigated. In the absence of EDTA, divalent cations inhibited photosynthetic C 0 2-fixation and PGA-reduction at low PGA concentrations, but had almost no effect on the reduction of OAA, BQ, and on PGA-reduction at high PGA concentrations. The inhibitory effect of Ca2+ was greater than that of M g2+. Inhibition of photosynthesis was greater when the divalent cations were added in the dark than when added in the light. In spite of its inhibitory effect, Mg2+ partially restored the Ca2+ inhibited photosynthesis, indicating the involvement of a Mg2+ /Ca2+ antagonism in the inhibitory effect. The inhibitory effect of divalent cations is stronger in a medium with low concentrations of K + than in the presence of 20 — 50 m M KC1. Mg2+ induced a release of plastidal K + and an in crease of stromal H + concentration. The results indicate that external Mg2+ in the absence of EDTA does not influence neither photosynthetic electron transport nor photophosphorylation, but inhibits the light activation of some enzymes of the carbon reduction cycle. The latter is assumed to be due to an acidification of the stroma pH and the decrease of endogenous K + level. Since the chloroplast envelope has only a very low permeability towards Mg2+, possible mechanisms are discussed by which M g2+ changes the properties of the chloroplast envelope and thus secondarily induces the observed effects.

	Title	Permeability of Plasma Membrane Vesicles to Ouabain and Mg2+ as a Factor Determining Rate of Binding of Ouabain to Na+ and K+ Dependent ATPase
	Abstract	N a+, K+-ATPase of the plasma membrane isolated from sheep kidney medulla exhibits functio nal asymmetry for the cardiac glycoside ouabain. In this vesicular membrane preparation the rate of binding o f ouabain was slow (time constant > 60 min) when the vesicles were incubated in the presence o f isotonic sucrose. Upon treatment o f the preparation with hypoosmotic shock or phos-pholipase A the initial rate of ouabain binding was enhanced at least 3 fold. In equilibrium a concentration of the ouabain-enzyme-complex was obtained which was about twofold that of the untreated vesicles. This result suggests two types o f ouabain binding sites with an approximate stoichiometry of 1 to 1. The stoichiometry seems to be maintained at high concentrations of ouabain where binding curves show a biphasic time course. Additional information about hetero geneity of binding sites comes through experiments in which the vesicles were treated with Mg2+ prior to the addition o f ouabain. A minor fraction of the binding sites were occupied by ouabain only after longtime incubation with Mg2+.

	Title	Magnesium Bis[D(-)-Mandelate] Dihydrate and Other Alkaline Earth, Alkali, and Zinc Salts of Mandelic Acid
	Abstract	, and zinc D(-)mandelates have been prepared from the parent mandelic acid and equivalent quantities (1:1 / 2:1) of the corresponding metal hydroxides in water. Colourless polycrystalline products are obtained from the aqueous solutions by evaporation of the solvent. The alkali, ammonium and strontium salts are anhydrous, the calcium and barium salts are monohydrates, the magne sium salt is a dihydrate, and the zinc salt a trihydrate. The crystal and molecular structure of the magnesium salt has been determined by single crystal X-ray diffraction methods (mono clinic, space group P2i, Z = 2). The lattice contains isolated complexes with hexacoordinate magnesium atoms chelated by two mandelate anions through one of their carboxylate oxygen atoms and the alcoholic hydroxyl group. Two water molecules in cis position are completing the octahedral coordination sphere. [MgtQITO^MfTO^] is thus a true mononuclear magnesium complex. Its stability and non-hygroscopic properties suggest its use as a magnesium and/or mandelate drug.
