Organodiphosphines in PtP2X2 (X = As, Ge or Te) derivatives – Structural aspects

Abstract

Structural data of cis-Pt(η2-P2L)(XL)2 (X = Ge or Te), cis-Pt(η2-P2L)(η2-X2L) (X = As, Ge or Te) and trans-Pt(η2-P,TeL)2 were classified and analyzed. The chelating ligands create varieties of metallocyclic rings, which open in the sequence: 83.1° (GeGeGe) < 83.8° (AsC2As) < 86.2° (PC2P) < 88.5° (PC2Te) < 89.7° (PC3P) ~ 89.7° (GeGe2Ge). The structural data are compared and discussed with the complexes of an inner coordination spheres Pt(η2-P2L)(XL)2 (X = O, N, CN, B, Cl, S, Se, Si, Br or I), Pt(η2-P2L)(η2- X2L) (X = O, N, S, Se or Si), and Pt(η2-P,SiL)2.
