The crystal structure was refined to Rw — 4.6% for 3617 reflections measured at 180 K. The Fe(II) ion is coordinated by six nearly equidistant ligands that form an almost regular octahedron suggesting low-spin configuration.

 Title    AsPh4[W (0)Cl3(HN3S2)]; Synthese, IR-Spektrum und Kristallstruktur  
 Abstract    O xo-trichloro-hydrocyclothiazeno-tungstate(V I), Synthesis, IR Spectrum, Crystal Structure V iolet crystals o f A sPh4[W (0)C l3(H N 3S2)] were obtained by partial hydrolysis o f A sP h4 [W Cl4(N 3S2)] in a saturated solution in C H 2C12/CC14. Its IR spectrum is reported. The crystal structure was determ ined by X-ray diffraction (2284 independent observed reflexions, R = 0.041). Crystal data: triclinic, space group P 1, Z = 2, a = 812.2, b = 1268.4, c = 1343.9 pm , a = 88.58, ß = 82.04 and y = 88.26°. The com pound consists o f A sPh4® cations and [W (0)C l3(H N 3S2) ]e anions in which the tungsten atoms have a distorted octahedral coordination with one oxo-ligand (171 pm), three chlorine atoms and two nitrogen atoms o f the planar (H N 3S 2) 2 0 ligand. The WN bond lengths are 183 and 226 pm; the longer WN bond is due to the hydrogen atom attached to its N atom and to the trans influence o f the oxo group. The crystal packing corresponds to one o f the types frequently found among tetraphenylphosphonium com ­ pounds with cations stacked to parallel columns.

 Title    Methylaminodiphenylborane — Application of n B, 13C, 14N, 15N NMR  
 Abstract    BC(pp)?r Interactions, N M R Spectra, R otation about the B N bond UB , 13C , 14N , 15N N M R is used to study m ethylam inodiphenylborane (1). Com pound 1 can be regarded as a m odel com pound for studying BN(pp)jr-, B C (p p)7r interactions, for determining the barrier to rotation about the B —N bond and for the application o f natural abundance 15N N M R to boron-nitrogen chemistry. The 13C N M R o f 1 shows a large splitting o f the uC (para) resonances (in contrast to reports on similar com pounds in the literature) as a consequence o f hindered rotation about the BN bond. The difference in the nC (para) nuclear shielding indicates different m esom eric interactions between the trigonal boron atom and the two phenyl groups.

 Title    Thermal Decomposition of Aromatic Thioureas [1]  
 Abstract    T herm al decomposition of aromatic and heteroarom atic thioureas in boiling chlorobenzene is a first-order reaction. The reaction involves intram olecular hydrogen transfer followed by a cleav­ age of the C -N bond which is the rate-limiting step. The rate constants of decom position have been determ ined and correlated with quantum -chem ical reactivity indices.
