Structure and assembly of a hexanuclear AuNi bimetallic nanocluster

Abstract

An Au₄Ni₂ nanocluster containing a square-planar [–PPh₂–Au–S–Au–]₂ ring and two nickel-pincer arms is reported here. Abundant intra- and inter-cluster noncovalent interactions promote the assembly of the nanocluster into a porous framework material. The assembly-dependent unique solubility and photoluminescence were also investigated.
