Anticancer study of heterobimetallic platinum(II)-ruthenium(II) and platinum(II)-rhodium(III) complexes with bridging dithiooxamide ligand

Three heterobimetallic platinum (II)/ruthenium (II) and platinum (II)/rhodium (III) complexes, A: Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}-[Ru (p-cymene)Cl], R = isoamyl; B: Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}[Rh (phpy)2], R = isoamyl; C: [Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}-[Rh(C5Me5)Cl]], R = benzyl, were prepared from mononuclear complexes 1 and 2, 1: [Pt (H-isoamyl2DTO)2]; 2: [Pt (H-benzyl2DTO)2], DTO = dithiooxamide, by reaction of 1 or 2 with the corresponding...
