Metall-Schwefelstickstoff-Verbindungen. 22. S4N3Cl als Ausgangsprodukt zur Herstellung von Komplexen mit dem S3N−-Liganden Die Komplexe [Ph6P2N][Cu3(S3N)2(CN)2]und [Ph4As][(CuS3N)2(CN)]

The reaction of S₄N₃Cl with metal salts leads to complexes containing the S₃N^?chelating ligand, a reaction which proceeds smoothly especially in an alkaline medium. Thus we were able to prepare, by the reaction of CuCN with S₄N₃Cl and Ph₆P₂N]OH (Ph = phenyl), the salt Ph₆P₂N]Cu₃(S₃N)₂(CN)₂], a compound in which the anions build a bidimensional network through supplementary Cu - S contact interactions. The salt is monoclinic, space group C2/c, a = 18.960, b = 14.651 and c = 15.400 Å, β = 101.03° and Z = 4. Metal Sulfur Nitrogen Compounds. 22. S₄N₃Cl as a Starting Compound for the Preparation of Complexes Containing the S₃N^? Ligand. Complexes Ph₆P₂N] Cu₃(S₃N)₂ (CN)₂] and Ph₄As] (CuS₃N)₂ (CN)] In contrast, the reaction of CuN with S₄N₃Cl and Ph₄As]OH led to the compound Ph₄As](CuS₃N)₂(CN)], monoclinic, space group C2/c, a = 18.478, b = 6.405, c = 27.051 Å, β = 119.50°, Z = 4. In the centrosymmetric anion the two Cu(S₃N) groups are linked together by disordered CN^? groups. An additional linkage results from Cu - Cu contact interactions, with d = 2.84 Å.
