| Abstract: | Synthesis and Crystal Structure of (AsPh4)2Cl5WNSNWCl5] . The chlorothionitrene complex WCl4(NSCl)]2 reacts with excess tetraphenylarsonium chloride via the intermediate AsPh4Cl5W(NSCl)] to yield the title compound. This was characterized by its i.r. spectrum and an X-ray crystal structure determination (4078 reflexions uncluding Friedel pairs, R = 0.059). (AsPh4)2Cl5WNSNWCl5] crystallizes in the monoclinic system, a = 1110.5, b = 1714.6, c = 1521.7 pm, β = 107.24°, Z = 2. The space group is either P21/n with anions statistically disordered in two different positions or Pn with an apparent higher symmetry due to the presence of inversion twins. Bond distances and angles correspond to the formula  |
