Ionic Platinum(II)-Imidobis(diphenylthiophosphinato) Complexes: Preparation, Structure, and Thermal Behavior

Abstract

The PPh2P(S)NHP(S)PPh2 (dppaS2) ligand reacts with the starting complexes PtCl2(L-L) (L-L = Ph2PCH2PPh2), (dppm), Ph2PCH2CH2PPh2 (dppe), Ph2PCH2CH2CH2PPh2 (dppp), and NaClO4 center dot H2O. Final products are monomeric complexes, and their formulas are [Pt(L-L)(dppaS2-H)] [(L-L = dppm(1), dppe(2), dppp(3)]. All of these have been characterized by 1H, 13C,31{P1H} NMR, FTIR, and elemental analysis. These complexes were also examined by TGA, DTA, and DSC analysis. Complexes 2 and 3 were crystallographically characterized.
