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.

1,4-Digerma-2-buten-1,4-diylplatinum(II) complexes were prepared by treatment of a (η-ethylene)(triphenylphosphine)platinum(0) complex with (Z)-α,β-bis(dialkylgermyl)styrenes, and their structures were determined by spectroscopic analysis coupled with X-ray diffraction methods. Thermolysis of 1,4-digerma-2-buten-1,4-diylplatinum(II) complexes afforded linear and cyclic trigermanes and a dinuclear platinum complex. The 1,4-digerma-2-buten-1,4-diylplatinum(II) complexes reacted with alkynes to give the corresponding insertion products, cyclic germy(germylvinyl)platinum(II) species, whose structures have been determined by spectroscopic analysis. The cyclic germy(germylvinyl)platinum(II) complexes were found to easily liberate 1,4-digermacyclohexa-2,5-dienes and a platinum(O) complex. The reactions of 1,4-digerma-2-buten-1,4-diylplatinum(II) complexes with carbon monoxide and isocyanides afforded the corresponding platinum complexes containing one carbon monoxide and one isocyanide ligand, respectively.
