Bis[chloridobis(triphenylphosphine)copper(I)-μ-chlorido]bis(1,2-diaminopropane)copper(II) acetonitrile disolvate

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.
