Crystal structure of catena -poly[[bis-( N -acethyl-thio-morpholine-κ S )copper(I)]-μ-iodido].

The reaction of copper(I) iodide with -acetyl-thio-morpholine (, CHNOS) in aceto-nitrile results in a coordination polymer with composition [CuI()] . The Cu atom is coordinated by two S atoms and two I atoms, adopting a distorted tetra-hedral environment. The μ-bridging mode of the I atoms gives rise to chains extending parallel to [010]. C-H⋯O hydrogen-bonding inter-actions between the chains lead to a three-dimensional network.
