Construction of heterobimetallic Cd(Hg)/Cu(Ag)/S(Se) complexes from homoleptic [Hg(EPh)2] molecules and [Cd(EPh)4]2− anions (E = S, Se)

Through the interactions of homoleptic [Hg(EPh)2] molecules and [Cd(EPh)4]2− anions (E = S, Se) as metalloligands with [M(PPh3)2Cl] or [M(PPh3)2NO3] (M = Cu, Ag), series of new heterobimetallic Cd(Hg)/Cu(Ag)/S(Se) complexes including neutral trinuclear [Hg(μ-EPh)2{CuCl(PPh3)2}2] and [Cd(μ-EPh)4{M(PPh3)2}2] and heptanuclear [Cd3(μ-EPh)6(μ3-EPh)4(AgPPh3)4] have been isolated and characterized. Their molecular structures and spectroscopic properties of these heterobimetallic complexes have been presented in this paper.
