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

The reaction of copper(I) iodide with N-acetyl-thio-morpholine (L, C6H11NOS) in aceto-nitrile results in a coordination polymer with composition [CuI(L)2] n . The Cu(I) atom is coordinated by two S atoms and two I atoms, adopting a distorted tetra-hedral environment. The μ2-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.
