The reaction of copper(I) iodide with tri-m-tolylphosphine (m-tolyl 3P) in acetonitrile yielded the cluster [Cu6(μ 2-I)(μ3-I)4(μ4-I)(m-tolyl 3P)4(CH3CN)2] (1), with a bicapped adamantoid geometry. In this compound, four Cu atoms are coordinated to four terminally bonded m-tolyl3P ligands, two Cu atoms are bonded to two CH3CN ligands, and iodide ligands have μ2-I, μ3-I, and μ4-I bonding modes. This compound has four Cul3P and two Cul3N cores, and geometry around each Cu center is distorted tetrahedral. The polarizable iodide ligand and the position of the methyl group in the phenyl ring attached to the P atom appear to have played the pivotal role in the formation of monomeric bicapped adamantoid geometry, which is unique in copper chemistry.
