 Title    IR-Spektren von Platin(II)-Komplexen mit Glycin, Glycin-und Glycylglycinethylester [1] IR-Spectra of Platinum(ll) Complexes with  
 Abstract    The infrared spectra (200-4000 cur 1) of trans-and cw?-Pt(NX2CH2COO)2 (X = H, D), trans-and cis-PtCl2(NH2CH2COOH)2, *rans-PtCl2(NH2CH2C02Et)2, cw-PtCl2(NX2CH2C02Et)2, cw-PtCl2(NX2CH2NXCH2C02Et)2 (X = H, D) and cis-PtY2(NH2CH2NHCH2C02Et)2 (Y = Br, I) including 15 N derivatives have been studied. There is no appreciable change of vibrat ional frequencies for corresponding eis-and trans-complexes which could be attributed to the irans-influence of different ligands. Due to lower symmetry most of the absorptions of the cis-complexes are split into doublets compared with the £rans-compounds.

 Title    Ferrocenylen-cobaltocenylenium  
 Abstract    hexafluorophosphat [(h 5 :h 5 '-C10H8)2FeCo] [PF6], ein gemischtkerniger Komplex vom Bis(fulvalen)dimetall-Typus Ferrocenylenecobaltocenyleniumhexafluorophosphate [(h 5 : h 5 '-CioH8)2FeCo][PF6], Ferrocenylenecobaltocenylenium-monochloride and ferrocenylenecobaltocenylenium-hexafluorophosphate were prepared under the aspect of influencing the valence averaging phenomena described for homodinuclear metallofulvalenes. Detected paramagnetism of the monocation is assumed to result from such interactions in dibridged rigid metallocenes. The above cation is characterized by IR, CV, MS, electron microprobe and elemental analyses.

 Title    ReCl5 * OPCl3; IR-Spektrum und Kristallstruktur ReCl5 -O PCl3; IR Spectrum and Crystal Structure  
 Abstract    Single crystals of ReCl5 • OPCl3 were obtained by cooling a saturated solution of rheniumpen­ tachloride in phosphorylchloride. It formes black needles, which are extremely sensitive to mois­ ture. In the IR spectrum v(PO) is shifted downwards by 140 cm-1 in comparison with liquid POCl3, indicating coordination via oxygen. The crystal structure was solved and refined from X-ray diffraction data (space group Pnma, four formula units per unit cell, a = 1629, b = 790, c = 877 pm, 902 observed, independent reflexions, R = 0.040). The complex forms discrete molecules ReCl5 • OPC1, with symmetry Cs (m). Bond lengths are Re —O — 214 pm and P —O = 146 pm, the angle Re —O —P is 143°.

 Abstract    [HC(NH 2) 2 ] 3 FeCl 6 was obtained together with other products from the reaction of S 4 N 4 with HCl in H 2 CC1 2 in the presence of FeCl 3 . Its crystal structure was determined from X-ray diffraction data (473 in-dependent observed reflexions, R = 0.047). Lattice constants: a = 961.6, c — 876.4 pm; tetragonal, space group P4 2 /m, Z = 2. Of the two crystallo-graphically independent formamidinium ions HC(NH 2) 2 ®, one exhibits positional disorder; the other one has C—N bond lengths of 128 pm. The FeCl 6 30 ions have symmetry C 2h , but the deviation from O h is small.

 Title    Low-Temperature Matrix Photochemistry of (f/ 4 -Diene)tetracarbonylchromium Complexes  
 Abstract    Photolysis of (^ 4 -diene)Cr(CO) 4 complexes (diene = butadiene, trans,trans-2,4-hexadiene, 2,3-dimethylbutadiene) in Ar, N 2 , and CO matrices at 10-12 K was monitored by infrared and UV-Vis spectroscopy. In argon and dinitrogen matrices loss of CO ist the predominant photoreaction. The resulting fac-(rf-diene)Cr(CO) 3 can take up N 2 from the matrix to form (?7 4 -diene)Cr(CO) 3 (N 2). In the case of the hexadiene complex this process requires matrix an-nealing subsequent to photolytic loss of CO. Photolysis in CO matrices, by contrast, results in stepwise displacement of the diene ligand, yielding (/7 2 -diene)Cr(CO) 5 and ultimately Cr(CO) 6 .

 Title    ji-Nitridokomplexe von Wolfram(VI) Die Kristallstruktur von PPh4[W2NCl10] /<-Nitrido Complexes of Tungsten(VI) The Crystal Structure of PPh4[W2NCl10]  
 Abstract    W2NC19 was obtained as a brilliant red crystal powder from tungsten hexachloride and tris(trim ethylsilyl)am ine. A ccording to its IR spectrum it has dimeric m olecules [W 2NC19]2 with bridging chlorine atom s. Its reaction with tetraphenylphosphonium chloride yields PPh4[W2N C l10], and with phosphorus oxide chloride W 2NCl9 O PCl3 is obtained; both are soluble in dichlorom ethane. The crystal structure of PPh4[W2N C l10] was determined_ by X-ray diffraction (2521 observed reflexions. R = 0.065). Crystal data: triclinic, space group P I , Z = 2, a = 1125.7, b — 1278.2, c = 1347.8 pm, a = 110.08, ß = 94.55, y = 111.55°. The structure consists o f PPh4® ions which are arranged to (PPh4®)2 pairs about inversion centres, and o f [W2N C l10]e anions. The latter possess an alm ost linear W NW group (173°) with slightly different WN bond lengths o f 179 and 188 pm corresponding to double bonds. Each tungsten atom has an octahedral coordination. The WC1 bonds trans to the nitrido ligand are about 9 pm longer than the bonds in the cis positions. 2. Synthesen und IR-Spektren der /i-Nitridokomplexe W2NC19 erhält man gemäß Gl.

Erhöht man die Temperatur, so findet bereits bei 20 °C langsam und ausschließlich die Bildung des auch auf andere Weise zugänglichen WNC13 [1] statt. Wählt man in diesem Fall das Mengenverhältnis der Reaktanden nach (1), so läßt sich schließlich die Hälfte des WC16 zurückgewinnen. Bei Anwendung molarer Mengen 1:1 erhält man direkt reines WNC13: WC16 + N(SiM e3) 3 2 0 °C > WNC13 + 3 Me3SiCl (2) Für den Mechanismus der Reaktion (1) nehmen wir einen stufenweisen Verlauf an, bei dem sukzessive Trimethylchlorsilan abgespalten wird. Erstes mögli­ ches Zwischenprodukt wäre dann Cl5WN(SiMe3)2, das wir allerdings nicht isolieren konnten.

 Title    Tetrazido-Nitrido-Molybdat(VI); Darstellung, IR-Spektrum und Kristallstruktur von AsPh4[MoN(N3)4] Tetrazido-nitrido-molybdate(VI); Preparation, IR Spectrum and Crystal Structure of AsPh4[MoN(N3)4]  
 Abstract    The complex AsPh4[MoN(N3)4] is prepared by the reaction of AsPh4[MoNCl4] with silver azide in dichloromethane suspension in the presence of dry sodium sulfate. The IR spectrum indicates an Mo=N group and four covalently bonded N3 groups for the [MoN(N3)4] e anion. AsPh4[MoN(N3)4] crystallizes in the triclinic space group P1 with two formula units in the unit cell. The crystal structure was solved by X-ray diffraction methods (R = 0,038; 4049 independent reflexions). The structure consists of AsPh4® cations and [MoN(N3)4] e anions. The short MoN bond length of the nitrido ligand (163 pm) corresponds to an Mo = N triple bond. The steric effects of the lone pairs of the a-N atoms of the azido groups with the MoN ligand cause a propellerlike twisted conformation of the four azido groups.

 Title    Platinum Blues -a Study of the Interaction between Potassium  
 Abstract    Potassium tetrachloroplatinate and asparagine form a paramagnetic complex in aqueous solution. This complex which displays a blue green color has been studied by ESR and IR spectroscopy. The ESR spectra are interpreted to be due to tervalent platinum in a low spin d 7 configuration. The IR data suggest that the doubly deprotonated ligand is co-ordinated through the COO -and CONH -groups.

 Title    Kristallographisches und spektroskopisches Verhalten einiger gemischter Phosphat/Vanadat-Fluoroapatite Crystallographic and Spectroscopic Behaviour of Some Mixed Phosphate/Vanadate Fluoroapatites  
 Abstract    Crystallographic data for m ixed phosphate/vanadate fluoroapatites o f the type M 1o(P0 4)6_J(V 0 4)AF2 (with M = Ca, Sr, Ba and x = 1—3) have been obtained from X-ray powder data. The only structural effect observed is a continuous increase of unit cell dim ensions with increased vanadate incorporation. The IR and Raman spectra show that the V 0 43 incorporation has a negligible effect on the strength of the P —O bonds, although a small bond weakening for both tetrahedral oxoanions is observed as the unit cell volum e increases. The results are com par­ able to those reported earlier for similar mixed hydroxyapatites and suggest that the fluoroapatite lattice can be considered as a good "m odel" for the vertebrate hard tissues.

 Title    Infrared, 57 Fe Mössbauer, and 31 P NMR Spectroscopic Characterization of Fe(CO) 4 L (L = Phosphine and Phosphite)  
 Abstract    A series of trigonal bipyramidal Fe(CO) 4 L complexes has been prepared and characterized by infrared, 57 Fe Mössbauer and 31 P NMR spectroscopy. A linear correlation, with a negative slope, between the CO stretching frequencies and the isomer shifts demonstrates that the triple bond nature of the carbonyl ligands is strengthened with increasing iron-to-phosphorus back donation. The linear dependence of the quadrupole splittings on the isomer shifts with a positive slope has revealed that the cr-donor capability of the phosphine or phosphite ligand is offset by the ^ • -acceptor capability. The formation of Fe(CO) 4 L complexes from the corresponding free ligands is accompanied by a downfield shift of 31 P NMR chemical shifts. The coordination shifts are linearly correlated with the Mössbauer isomer shifts.

 Title    N-TrimethylsilyMminotriphenylphosphoran-Kupfer(II)-chlorid, (Me 3 SiNPPh 3 * CuCl 2 ]2 Synthese und Kristallstruktur N-Trimethylsilyl-iminotriphenylphosphorane Copper(II) Chloride, [Me 3 SiNPPh 3 * CuCl : ] 2 Synthesis and Crystal Structure  
 Abstract    The title compound has been prepared by the reaction of N-trimethylsilyl-iminotriphenylphos-phorane with copper(II) chloride in boiling CCl 4 /C 2 H 5 OH, and forms moisture sensitive crystals, which are green in transmittance and black in reflexion. [Me 3 SiNPPh 3 • CuCl 2 ] 2 was characterized by its IR spectrum as well as by a crystal structure determination (4197 observed, independent reflexions, R = 0.049). The lattice dimensions are at 20 °C: a = 1102.7. b = 1407.3. c = 1560.2 pm; ß = 94.27°; space group P2,/« with two formula units in the unit cell. The complex consists of centrosymmetric, dimeric molecules with a planar Cu 2 Cl 2 ring (Cu —CI bond lengths 229 and 231 pm). A terminally bonded CI atom (Cu —CI = 221 pm) and the N atom of the Me,SiNPPh 3 ligand (Cu —N = 198.5 pm) complete the coordination number four of the nearly planar surroundings of the Cu atoms.
