Homo- and hetero-, bi- and tri-nuclear palladium(II) and platinum(II) complexes containing single bridging chalcogenolate of a metallo-ligand, [MCl(ECH2CH2NMe2)(PR3)] (MÂ =Â Pt, Pd; EÂ =Â Se, Te)

Bi- and tri-nuclear complexes of the types [MCl(ECH2CH2NMe2)(PR3)M′Cl2(PR3)] and [{PtCl(SeCH2CH2NMe2)(PR3)}2M′Cl2] (M, M′ = Pd, Pt; E = Se, Te) have been prepared. The molecular structure of [{PtCl(SeCH2-CH2NMe2)(PEt3)}2PtCl2] comprises of three square planar platinum atoms which are held together by the single bridging selenolate group in a linear chain arrangement.
