【 摘 要 】

The title compound, [Cu4(C9H11)4(C3H9P)2] or [Cu4(Mes)4(PMe3)2] (Mes = 2,4,6-trimethylphenyl), was synthesized from copper(I) mesityl and trimethylphosphane in THF as solvent. The molecular structure of the complex has C2 symmetry and consists of four copper(I) atoms bridged by four μ-mesityl groups, giving an eight-membered puckered {Cu4C4} ring. Additionally, two copper(I) atoms at opposite corners of the Cu4 rhomb are each linked to a terminal PMe3 ligand. The PMe3-bearing copper(I) atoms exhibit a distorted trigonal–planar coordination mode whereas the remaining Cu atoms linked to two mesityl groups are nearly linearly coordinated.
