Novel selenolato-bridged dinuclear hydridoplatinum complexes, cis-[Pt 2H2(μ-SetBu)2(PPh 3)2] (2) and cis-[Pt2H(SetBu)(μ- SetBu)2(PPh3)2] (3) were synthesized in 30% and 57% yields, respectively, by the thermolysis of hydrido(1,1- dimethylethaneselenolato) Pt(II) complex cis-[PtH(SetBu)(PPh 3)2] (1) in toluene at 80 °C for 3 h. The structures of dinuclear complexes 2 and 3 were fully characterized on the basis of their NMR and IR spectroscopic data and X-ray crystallography. The two distorted square planar Pt atoms in 2 and 3 are held together by two bridged selenolato ligands, tBu groups of which adopt a trans configuration with respect to the four-membered Pt2Se2 ring. Each central Pt 2Se2 ring in 2 and 3 has a hinged arrangement due to the steric repulsion among the two PPh3 ligands and the tBu group lying between them.
