N2 - Mononuclear and dinuclear Pd(II) complexes with mercapto-1,3,4- thiadiazolate were prepared by reacting [Pd-(OH)(terpy)](PF 6) with 2-amino-5-mercapto-1,3,4-thiadiazole (Hamct) and 2,5-dimercapto-1,3,4- thiadiazole (H 2dmct). The reaction of [Pd(OH)(terpy)](PF 6) and [Pt(Hdmct)(terpy)](PF 6) resulted in the formation of the Pd(II)-Pt(II) heterometallic complex [{Pd(terpy)}(μ-dmct-S,S′) {Pt(terpy)}](PF 6) 2, which showed that dmct 2- can be utilized to prepare rationally heterometallic systems. Crystal structure analysis of the complexes showed that the ligands coordinate to the Pd(II) and Pt(II) centers by their mercapto groups in a κ 1S coordination mode. The electronic spectra, redox properties, and molecular orbitals of the palladium complexes have been compared to those of Pt(II) congeners that we reported previously. The properties of a Pd(II)-Pt(II) mixed metal complex were elucidated based on the properties of each metal center.
