 Title    Über die Wechselwirkung des Vanadyl(IV)-Kations mit Calcium-Hydroxylapatit The Interaction of the Vanadyl(I V) Cation with Calcium Hydroxylapatite  
 Abstract    Solid products obtained from calcium hydroxylapatite suspensions in diluted V 0 2+ solu­ tions, under different experimental conditions, were investigated by means o f X-ray powder diffractometry and IR and ESR spectroscopy. It is demonstrated that the V 0 2+ cation cannot be incorporated into the apatite-lattice but is strongly adsorbed on the surface o f the material. Different aspects o f this adsorption were thoroughly investigated. The ESR spectra suggest an inhom ogeneous distribution o f the adsorbed species and the generation o f 0 = V (0)4 moieties, which show a high stability towards oxidation.

 Title    Über die thermische Zersetzung von N 2H6[CrF5(H20)] und die neue Verbindung N2H6CrF5  
 Abstract    Thermal decomposition of N 2H 6[CrF5(H 20)] has been investigated by thermoanalytical, X-ray and IR spectroscopic methods. U nder quasi-isobaric conditions the decomposition takes place in several steps. The intermediate N 2H 6C rF 5 has been found which crystallizes monoclinically with a = 555.0 pm, b = 1084.6 pm, c = 777.0 pm,/? = 91.76°. N 2H 6C rF 5 decom­ poses via an am orphous intermediate to give pure rhomboedrical C rF 3 as the final product. One of the intermediate has been identified as chrom ium fluoride am moniate C rF 3-0.4 N H 3. No hydrolysis reactions have been observed.

 Title    Darstellung, "B-NMR-und Schwingungsspektren der ctoso-Hexaborate |B6(SCN)6]J-und [B6(SeCN)6]2  
 Abstract    On treatment o f [N(C4H 9)4][B6H 7] with (S C N)2 or (SeC N)2 in dichloromethane in the pres­ ence o f solid KOH the hexaborates [N(C4H 9)4]2[B6(SC N)6] and [N(C4H9)4]2[B6(SeC N)6] are formed. The octahedral structure for the B6 cage is proven by "B N M R spectroscopy. The chemical shifts in relation to BF3 • OEt2 o f —9,7 (SC N) and -10,2 ppm (SeC N) show the influ­ ence o f -I and +M effects o f the substituents. The S(Se) coordination is deduced from vibra­ tions within the substituents: vCN is observed at frequencies higher than 2100 cm -1 in the IR and Raman spectra, vcs at 662 and vcs at 556 cm "1 (intense IR bands).

The pure com pounds have been separated by ion exchange chro­ matography on diethylaminoethyl cellulose. Their structures are proved by "B N M R spectra which show the features o f substituted B6 cages with C4v and D 4h point symmetry. Due to the + M effect o f the nitrito group in contrast to the -M effect o f the nitro substituents character­ istic "B chemical shifts o f opposite sign have been observed.

 Title    Preparation and Properties of Rhodium(III) Complexes with the T etr adentate Ligand N,N'-Bis(2'-py ridi neearbox am ide)-1,8-naphthalene  
 Abstract    Synthetic procedures are described that allow access to a number of new Rh(III) complexes with the tetradentate bis-amide ligand N,N'-bis(2'-pyridinecarboxamide)-1,8-naphthalene (LH2). These complexes have the formulae Rh(LH2)Cl3, Na[RhLX2] • H20 (X = Cl, CN) and [RhLA2]C104 (A = pyridine, 1-methylbenzotriazole). The compounds have been characterized by elemental analyses, conductivity measurements, X-ray powder patterns, spectroscopic (IR, UV/VIS, 'H NMR) studies and electrochemical methods. The neutral amide behaves as a bis-bidentate ligand in the oligomeric or polymeric, octahedral complex Rh(LH,)Cl3. Monomeric, trans octahedral structures are assigned for the complexes o f L2" in the solid state; the doubly deprotonated ligand acts as a tetradentate chelating agent with the four nitrogens as ligating atoms.

 Title    Synthese und Reaktivität von 7-Triphenylstannyl-a-am inobuttersäure- derivaten  
 Abstract    Ph3SnCH2CH 2C H (NHCOOCH 2P h)COOCH3 (1) is synthesized by hydrostannation of methyl N-(benzyloxycarbonyl)vinylglycinate with Ph3SnH. The reaction o f 1 with HC1 in CH 3OH and with bromine in CHC13 yields the halostannylsubstituted compounds Ph3_"X,?SnCH2CH 2C H(NHCOOCH 2Ph)C OOCH3 (2 -4) (n = 1, 2; X = Cl, Br). By sapo­ nification with one equivalent of NaOH and subsequent acidification with HCl 1 is transformed into the free acid Ph3SnCH2C H 2C H(NHCOOCH2Ph)COOH (5) that undergoes cyclization into the 1,2-oxastanninane 6 with intramolecular elimination of benzene. IR, NMR data and the determination of the crystal structure of Ph2BrSnCH2CH2CH(NHCOOCH2Ph)COOCH3(3) reveal for 2 and 3 an intramolecular coordination of the N C (0)0-group at the tin atom to form a seven-membered ring.

 Abstract    By treatment of [PtCl6]2-with an excess of SCN~ in aqueous solution [Pt(SCN)6]2~ is formed. The X-ray structure determination on a single crystal of [Py2CH2][Pt(SCN)6] (orthor-hombic, space group Pna21? a = 15.5084(9), b = 11.8444(11), c = 13.2830(9)A, Z = 4) shows, that the thiocyanate groups are exclusively S-coordinated with average Pt-S distances of 2.378 A and Pt-S-C angles in the range from 103.1° to 108.1°. Based on the molecular parameters of the X-ray determination the low temperature (10 K) IR and Raman spectra have been assigned by normal coordinate analysis. The valence force constant is fd(PtS) = 1.62 mdyn/A.

 Abstract    [CO(CO)2(R2PCH2)3CCH2PR2][CO(CO)4] (R = C6H5) was synthesized in a simple manner from Co2(CO)s and the tetratertiary phosphine C[CH2P(C6H5)2]4, which acts only as a tridentate ligand. [Co(CO)2(R2PCH2)3CCH2PR2][Co(CO)4] reacts with NH4PF6, NaBH4, NaBD4 or liquid ammonia at 20 °C to [Co(CO)2(R2PCH2)3CCH2PR2]PF6, CoH(CO)2(R2PCH2)2C(CH2PR2 • BH3)2, CoD(CO)2(R2PCH2)2C(CH2PR2 • BD3)2 or Co(CO)(CONH2)(R2PCH2)3CCH2PR2. In liquid ammonia [Co(CO)2(R2PCH2)3CCH2PR2][Co(CO)4] at 60 °C yields the hydride CoH(CO)(R2PCH2)3CCH2PR2. The new compounds were characterized, as much as possible, by their IR, Raman and 1 H NMR data.

 Title    A New Preparation of S4N4  
 Abstract    Pure S4N4 is prepared by a new method from reduction of S3N3CI3 by various metals (Hg, Cu, Sn). Realized either in an inert solvent or directly in gaseous phase the reaction is complete. The stability range of NSC1 has been determined by Raman spectrometry. Tetrasulfur tetranitride is a very interesting product because it is the starting material for many products containing sulfur and nitrogen. In the usual method S4N4 (1) is prepared by bubbling gaseous ammonia through a solution of sulfur di-chloride dissolved in an inert solvent: 16 NH3 + 6 SCls -> S4N4 + 12 NH4C1 + 2 S Besides S4N4, NH4C1 and S, the S7NH imine is also formed in small quantity. NH4CI is easily eliminated by iced water. The separation of S4N4 from the obtained mixture is difficult. The three compounds (S4N4, S7NH and S) have similar molecular struc-tures (puckered eight-membered rings), they have similar solubilities in solvents and are difficult to separate from one another. The extraction of S4N4 by dioxane permits to partly eliminate sulfur. S4N4 can be purified by chromatography on an alumina column (2), benzene, a good solvent for S4N4, is used for its elution. By sublimation under vacuum it is possible to eliminate sulfur from S4N4, but this method is dangerous due to the explosive character of S4N4. The methods of purification are long and not always very efficient. For the first time, we have prepared S4N4 in a high purity grade from S3N3CI3 which can be easily obtained (3). This new method consists in the action of reducing metals such as Hg, Cu or Sn on S3N3CI3 either in an inert solvent or directly in gaseous phase. The identification and the stability of the different gaseous compounds have been studied by infrared and Raman spectro-scopy.

 Title    Dicarbonyl-, Carbamoyl-carbonyl-und Carbomethoxo-carbonyl-Komplexe des Rhodiums mit tri-und tetratertiären Phosphinliganden [1] Dicarbonyl-, Carbamoyl-carbonyl-and Carbomethoxo-carbonyl Complexes of Rhodium with Tri-and Tetratertiary Phosphine Ligands [1]  
 Abstract    The cationic dicarbonyl complexes [Rh(CO)2(R2PCH2)3CR']PF6 (R = C6H5; R' = CH3, -CH2PR2), formed by high pressure synthesis from RhCl3(H20)3, CO and (R2PCH2)3CR' react with liquid ammonia at 20 °C to give the carbamoyl complexes Rh(CO)(CONH2)(R2PCH2)3CR'. At 100 °C in liquid ammonia the carbamoyl-carbonyl complexes Rh(CO)(CONH2)(R2PCH2)3CR' form the CO-bridged, dinuclear compounds (^-CO)2[Rh(R2PCH2)3CR']2. Upon treatment of Rh(CO)(CONH2)(R2PCH2)3CR' with CH3OH the carbomethoxo carbonyl complexes Rh(CO)(COOCH3)(R2PCH2)3CR' are obtained. The new compounds were characterised, as far as possible, by their IR, Raman and 31 P NMR spectra.

 Title    Anhydrous Chromium(III) Carboxylates: Reactions of Cr03 with Carboxylic Acid Anhydrides  
 Abstract    Chromium(VI) oxide reacts with excess of carboxylic acid anhydrides [(RC0)20 where R = CH3, C2H5, n-C3H7 and CHCI2] to give pure chromium(III) carboxylates. Their IR and 1H NMR spectra suggest the presence of two different types of carboxylate groups. Magnetic susceptibility and absorption spectra favour an octahedral geometry around Cr.
