Synthesis and characterisation of four bimetallic gold-gallium clusters with Au-Ga rings as a new structural motif in gold cluster chemistry.

ABSTRACT: Using the newly introduced reducing agent in gold cluster chemistry GaCp, four new bimetallic gold-gallium cluster compounds were synthesised, stabilised by alkylphosphine ligands. The gold core of Au₆(GaCl₂)₄(PEt₃)₆, Au₇(GaCl₂)₃(P ⁿ Pr₃)₆ and Au₁₃(GaCl₂)₅(GaCl)(P ⁿ Pr₂ ⁿ Bu)₉ is composed of two, three and four Au₄ tetrahedra, linked in different ways. This arrangement gives the last-mentioned cluster the shape of a five-pointed star. A fourth synthesised metalloid gold cluster Au₁₃(GaCl₂)₅(P ⁿ Pr₃)
