S4N4 und seine Derivate: Isolierung und Struktur von Pd2(S3N)2(S3N2) / S4N4 and its Derivatives: Isolation and Structure of Pd2(S3N)2(S3N2)

Abstract

Abstract The reaction of S4N4 with PdCl2 in methanol yields among other products the dinuclear complex Pd2 (S3N)2(S3N2) (D): dark red needles, space group R"3̄ with a = 32.759(15), c = 6.516(4) Å and Z = 18. The structure of D was determined by an X-ray analysis. Each palladium atom is part of an almost planar PdS3N metallocycle. The SNSNS group acts as a bridge whereby each of its terminal S atoms is bonded to both Pd atoms. The Pd atoms possess a square planar coordination by four S atoms. The coordination planes form an angle of 114.9°. The Pd-Pd distance of 2.921(2) Å is rather short.
