Abstract: The title complex, [Au₂(C₁₇H₁₁N)₂(C₁₂H₁₀P)]ClO₄·C₂H₃N, contains two Au^III atoms bridged by a diphenylphosphanide ligand. Each Au atom is in a square-planar environment coordinated by diphenylphosphanide and 2,6-diphenylpyridine ligands. There are weak - stacking interactions between neighbouring molecules (the interplanar separations between two neighbouring dpp units are 3.40 and 3.57 Å). The intramolecular AuAu separation is 3.788 (5) Å. The crystal structure shows weak intermolecular C-HO and C-HN hydrogen bonds involving an O atom of the perchlorate counter-ion and the N atom of the acetonitrile solvent molecule, respectively.
