Mn(II)-cu(I) hybrid complex based on 1,3,5-tris(diphenylphosphinyl)benzene

Abstract

The reaction of 1,3,5-tris(diphenylphosphinyl)benzene (L) with MnI2 in the presence of CuI (wet MeCN, 25°C, 30 min) leads to the formation of a complex [MnL4(H2O)2][Cu5I7(CH3CN)]·7MeCN with yield of 72%. The Mn2+ ion of this complex has a distorted Mn@O6 octahedral environment formed by four L ligands and two coordinated water molecules. The [Cu5I7(CH3CN)]2- anion has an unprecedented structure of the {Cu5I7} backbone, which includes five copper atoms bound by bridging iodide ions (µ2, µ3, µ4), as well as four short Cu···Cu contacts (
