Abstract: The title complex [systematic name: bis(1,2-diaminopropane-2²N,N')di--chlorido-1:2²Cl,2:3²Cl-dichlorido-1Cl,3Cl-tetrakis(triphenylphosphine)-1²P,3²P-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 Cu^II atom is bridged by Cl atoms to the two Cu^I atoms. The coordination geometry is octahedral for Cu^II, with Jahn-Teller elongation of the Cu-Cl bonds, and distorted tetrahedral for Cu^I, 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-HCl hydrogen bond each with a terminal Cl atom.
