title: Crystal structure of di-μ-iodido-bis-[bis(aceto-nitrile-κN)copper(I)].
abstract: The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu⋯Cu distance = 2.7482 (11) Å], the Cu(I) atoms of which are further coordinated by four mol-ecules of aceto-nitrile. The Cu(I) atom has an overall distorted tetra-hedral 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 aceto-nitrile 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 inter-actions present, so the crystal packing seems to be formed predominantly by van der Waals forces.
