Sulfur-bridged linkage of [Ni(thiolato)(2)(amine)(2)]-type complexes with linear gold(I) ions assisted by aurophilic interaction
The reaction of [Ni(aet)(2)] (act = -SCH2CH2NH2) with Au-I in water gave a S-bridged (Ni2Au2I)-Au-II? tetranuclear structure in [Au-2{Ni(aet)}(2)](2+), while the corresponding reaction using [Ni(L)] (L = [-SCH2CH2N=C(CH3)-](2)) led to the formation of a (Ni4Au4I)-Au-II octanuclear structure in [Au-4{Ni(L)}(4)](4+). Their molecular structures exhibiting aurophilic interactions were established by X-ray crystallography.
