Abstract
Three kinds of platinum(II) complexes, [Pt{S=C(NHEt)2}2h(PPh3)2](hfac)2, (2; R = Et or H, X = hfac) and (R = Et (3a) or H), containing thiourea derivatives as neutral, monoanionic, and dianionic ligands, respectively, have been prepared. Thioureido(1−) complex 2 (R = Et, X = OTs) was also prepared by protonation of 3a with TsOH·H2O. The structure of 3a with an N,S-chelating thioureido(2−) ligand was determined by single-crystal X-Ray diffraction.This publication has 10 references indexed in Scilit:
