 Title    Two Modifications of Tetraethylammonium tranis-Diiodobis(ethanedialdioximato)cobaltate(III) with and without Intermolecular 1--I Interactions  
 Abstract    The structures of two modifications of [C 8 H 2 nN][C4H 6 Col2N 4 04], M r -617.11, have been deter-mined by X-rav investigations. Form 1 is orthorhombic, Pben, a = 8.417(2), b — 12.923(3), c = 18.444(3) A, V = 2006 Ä 3 , Z = 4, d c = 2.04 gem" 3 , final R w = 0.037 for 1989 reflections and 124 parameters. There are no unusual intermolecular interactions in this modification. From 2 is tetragonal, \A x md, a = 8.886(3), c = 25.841(6) Ä, V = 2040 Ä 3 , Z = 4, d c = 2.01 gem" 3 , final R w = 0.027 for 1629 reflections and 80 parameters. In this modification the metal complexes form strictly linear chains via short intermolecular I -I contacts, 3.722(1) Ä.

 Title    EPR-Spektren von Tetrachlorocupraten verschiedener Aminothiazoliumderivate. Die Kristallstrukturen von 2-Amino-2-thiazolinium-und 2-Amino-4-methylthiazoliumtetrachlorocuprat(II) EPR Spectra of Tetrachlorocuprates of Several Aminothiazolium Derivatives. The Crystal Structures of 2-Amino-2-thiazolinium and 2-Amino-4-methylthiazolium Tetrachlorocuprate(II)  
 Abstract    The tetrachlorocuprates. of the 2-aminothiazolium ion and of four of its substitution products, of 2-aminothiazolinium, and of 2-amino-4-carboxyl-thiazolidinium ions were prepared from the cor-responding heterocyclic bases, hydrochloric acid and copper(II) chloride in ethanol. The thermo-chromic compounds were characterized by their IR and electronic spectra. The EPR spectra of solutions, frozen solutions, and of the solids show the CUC14 2 ~ ion to have the structure of a flattened tetrahedron; in the case of some of the solids, distortions from D 2 d symmetry are observed. This was confirmed by two X-ray crystal structure determinations. Crystal data: 2-amino-2-thiazolinium tetrachlorocuprate, monoclinic, space group C2/c, a = 2772.8, b = 780.0, c = 1560.0 pm, ß = 112.04°, Z = 8 (R = 0.047 for 2527 observed, independent reflexions); 2-amino-4-methylthiazolium tetrachlorocuprate, triclinic. PI, a = 780.4, b = 853.4, c — 1381.4 pm, a = 103.50, ß = 99.39, y = 104.17°, Z = 2 (R = 0.041 for 3319 reflexions). In both compounds the flattened CuCl 4 2 " tetrahedron is distorted and has two bond angles in the range between 130 and 141°. The heterocyclic cations are protonated at their ring N atoms; the corresponding H atoms and the H atoms of the amino groups are involved in N — H--C1 hydrogen bonding.

 Title    Cyclodi-und -trisilazane — Synthese, Reaktionen und Ringkopplungen Cyclodi-and -trisilazanes — Synthesis, Reactions and Ring Coupling  
 Abstract    Contrary to our expectations, a cyclotrisilazane is obtained instead of a cyclodisilazane by the reaction of the lithiated di-rerf-butyldiamino-silane with Hal 2 SiMe 2 . Mono-and disubstitution takes place in reactions of lithiated tetra-isopropyl cyclodisilazane with halogeno-silanes and -boranes. A disubstituted ring reacts with LiOC 4 H 9 -formed from LiC 4 H y and THF — to give an unsymmetrically substituted four-membered ring as proved by a crystal structure determination. Coupling of four-and six-membered rings occurs in the reaction of SiF-substituted and lithiated rings.

 Abstract    receivedJune30/September8,1986 'H/ 13 C NMR, Pyrophthalones, Solvent Dependent Structure The complete analysis of the 'H/ 13 C NMR spectra of a-Pyrophthalone and related compounds demonstrates that the earlier static planar description of the molecules is invalid for polar sol-vents, and here the stability of any intramolecular hydrogen bond is small.

 Title    Zur Polymorphie des Cadmiumsulfits, Kristallstrukturen von CdS0 3 -I, CdS0 3 -II und CdS0 3 -III Polymorphic Cadmium Sulfites, Crystal Structures of CdS0 3 -I, CdS0 3 -II, and CdSO r III  
 Abstract    The crystal structures of the anhydrous cadmium sulfites CdS0 3 -I (¥2 x /c, Z=4), CdS0 3 -II (P2/C, Z=8), and CdS0 3 -III (R3, Z=18 for the hexagonal cell) have been determined by means of single crystal X-ray diffraction data. The final R for the 1475, 2349, and 2138 observed reflections are 0.040, 0.034, and 0.073. Coordination of Cd is trigonal-prismatic, a hitherto unknown coordination of Cd in salts of oxoacids, in CdS0 3 -I and CdS0 3 -II, and octahedral in CdS0 3 -III. The Cd0 6 -polyhedra are arranged in two-dimensional (CdS0 3 -I) and three-dimensional (CdS0 3 -II and CdS0 3 -III) networks. S0 3 2-groups act as monodentate and in CdS0 3 -I and CdS0 3 -II also as bidentate ligands. Cd—O distances range from 224.5(3) to 244.6(3) pm, with an average of 231.5 pm for the trigonal-prismatic and of 231.0 pm for the octahedral coordination. S—O dis-tances range from 152.3(3) to 155.3(3) pm with an average of 153.7 pm, the O —S—O angles from 99.2(2) to 106.7(3)° with an average of 103.2°.

 Title    Konkurrierende Koordination von Kronenethern, Perchloratanionen und Lösungsmittelmolekülen am Co(II)-Ion — Eine Leitfähigkeits-und NMR-Studie in Nitromethan Anions and Solvent Molecules at Co(II)-Ions — A Conductivity and NMR Study on Nitromethane  
 Abstract    The 1:1 complexes between Co(II) and the crown ethers dibenzo[24]crown-8, dibenzo[18]-crown-6 and [18]crown-6 show a molar conductivity in nitromethane which indicates coordination of even Perchlorate anions. The substitution of this anion by solvent molecules can be monitored by conductometric titrations. This procedure reveals that dibenzo[24]crown-8 and [18]crown-6 is a potent five dentate ligand whereas dibenzo[18]crown-6 strongly coordinates only via three donor atoms. The mixed complexes with crown ether and methanol show strong outer-sphere associa-tion with the Perchlorate anions, which can be confirmed by investigations with [15]crown-5 complexes.

Reaction of Phosphorus Selenide with Iodine, Structure of P 3 Se 4 I, 31 P NMR Spectra P 3 Se 4 I is formed by the reaction of molten P 4 Se 3 and I 2 . P 3 Se 4 I is monoclinic, space group P2,/c with the lattice parameters of a = 1130.3(3) pm, b = 654.5(2) pm, c -1420.5(4) pm, ß — 117.64(2)°. d = 3.87 gem" 3 and d v = 3.82 gem" 3 for Z = 4. The structure of the molecule is derived from the structure of a-or /?-P 4 Se 3 I 2 by the substitution of a P—I group by a Se-atom. The P—I, P —P and Se — Se bond lengths are 249.9, 219.2 and 236.9 pm. resp. The mean P—Se bond length is 225.0 pm. The molecule is stabilized by two weak intramolecular P—Se and P—I bonds, comparable to the bonding situation in a-P 4 Se 3 I 2 . The 31 P NMR spectra reveal a coalescence effect, due to equilibrium between two isomeric forms of the molecules.

Synthesis and Structure of 5-Trichloromethyltetrazole  
 Abstract    The cycloaddition of nitriles and of dimethylacetylenedicarboxylate to the azide ligand of polymeric Schiff Base cobalt(III) and phosphine palladium(II) complexes gives the corresponding tetrazolate and triazolate complexes from which the heterocycles could be cleaved by hydrogen chloride. Usually the yields are low; if the heterocycle is soluble in ether or sublimable, yields up to 30% have been obtained. Using this method the hitherto unknown 5-trichlormethyltetrazole could be prepared which was characterized by an X-ray structural analysis. Similarly, the cyclo-addition of azido(tetraphenylporphinato)cobalt(III) with nitriles, cyclohexylisocyanide and Me0 2 CC=CC0 2 Me affords the corresponding complexes with heterocyclic ligands. The prepa-ration of tetraphenylporphyrinato(tricyanmethanido)cobalt(III), (TPP)CoN-CC(CN) 2 , is reported.

 Abstract    A series of alkyl-arylsubstituted N-methyl phosphinothioformamides, R(Ph)PC(S)NHMe (2 a—g), with varying bulkiness of the alkyl rest was synthesized from the racemic secondary phosphines la—g and methyl isothiocyanate. 'H and 13 C NMR spectra of 2a—g reveal signal sets of diastereotopic nuclei due to the asymmetry of the molecule. The chemical shift and coupling constants were confirmed by simulation in case of 2b, c. The vicinal 31 P— 13 C cou-plings of the menthyl and neomenthyl compounds 2f, g show an "anti-Karplus" behaviour CJ(gauche) > ? J(trans)) and allow the conformational assignment of the alicyclic group. The 31 P chemical shifts of 2a—d give a linear correlation with the cone angle of the alkyl substituents quoted from literature.
