Abstract
The title complex [systematic name: bis(1,2-diaminopropane-2κ2N,N′)di-μ-chlorido-1:2κ2Cl,2:3κ2Cl-dichlorido-1κCl,3κCl-tetrakis(triphenylphosphine)-1κ2P,3κ2P-tricopper(I,II,I) acetonitrile disolvate], [{(Ph3P)2Cl2Cu}2Cu(C3H10N2)2]·2C2H3N, is a centrosymmetric linear trinuclear mixed-valence copper complex in which the central CuII atom is bridged by Cl atoms to the two CuI atoms. The coordination geometry is octahedral for CuII, with Jahn–Teller elongation of the Cu—Cl bonds, and distorted tetrahedral for CuI, with a wide P—Cu—P angle. The diamine ligands are twofold disordered, with occupancy factors of ca 0.6:0.4, and form one N—H⋯Cl hydrogen bond each with a terminal Cl atom.
