| Trithiazylchloride, (NSC1)3, reacts with metallic chrom ium, with chromium hexacarbonyl, with CrCl3-3 thf, as well as with chrom ium (VI) oxide to form mixtures, in which S4N 3®[CrCl4(N 2S2) ] 0 can be identified as the major product. This com pound reacts with tetraphenylarsonium chloride in dichlorom ethane to form the title com pound, which we have characterized by IR spectroscopy and an X-ray crystal structural analysis. (A sP h4)4[CrCl4(N 2S2)]4 -8 C H 2C12 crystallizes m onoclini-cally in the space group C 2 /c with four formula units per unit cell and with the follow ing lattice constants at —100 °C: a = 2146, b = 2033, c = 3137 pm; ß = 96.0° (9918 independent observed reflexions, R = 0.064). The com pound consists o f A sPh4® ions, tetrameric anions [CrCl4(N 2S2)]44e and included C H 2C12 m olecules. The chromium atom s of the anions occupy the corners o f a nearly ideal square; they are connected via the N -atom s o f planar N 2S2-rings, which are oriented perpendicularly to the Cr4-plane. The chromium atom s com plete their distorted octahedral coordination with four terminal chlorine atom s, the axial ones o f which form short Cl---S-contacts o f average 310 pm to the S-atom s o f the N 2S2-rings. | | | |
