Crystal structure of di-μ-iodido-bis[bis(acetonitrile-κN)copper(I)]

Abstract

The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu...Cu distance = 2.7482 (11) Å], the CuI atoms of which are further coordinated by four molecules of acetonitrile. The CuI atom has an overall distorted tetrahedral coordination environment evidenced by L—Cu—L angles (L = N or I) ranging from 100.47 (10) to 117.06 (2)°. The coordination geometries of the acetonitrile ligands deviate slightly from linearity as shown by Cu—N—C angles of 167.0 (2) and 172.7 (2)°. In the crystal, there are no significant hydrogen-bonding interactions present, so the crystal packing seems to be formed predominantly by van der Waals forces.
