Sulfur-bridged Linkage of [Ni(thiolato)2(amine)2]-type Complexes with Linear Gold(I) Ions Assisted by Aurophilic Interaction

Abstract

Abstract The reaction of [Ni(aet)2] (aet = −SCH2CH2NH2) with AuI in water gave a S-bridged NiII2AuI2 tetranuclear structure in [Au2{Ni(aet)}2]2+, while the corresponding reaction using [Ni(L)] (L = [−SCH2CH2N=C(CH3)–]2) led to the formation of a NiII4AuI4 octanuclear structure in [Au4{Ni(L)}4]4+. Their molecular structures exhibiting aurophilic interactions were established by X-ray crystallography.
