Reactions of N,N′-diethylthiourea (Detu) with copper(I) cyanide and copper(I) iodide in a 2:1 M ratio in acetonitrile resulted in the formation of [Cu(Detu)Cl]3·(CH3CN)0.5 (1) and [Cu(Detu)3I] (2), respectively. In compound 1 each copper atom is coordinated with one sulfur atom of Detu and with one chloride ion forming a centrosymmetric trinuclear core (Cu3S3Cl3) that exhibits a Cu–Cu separation of 2.7383(5) Ǻ indicating the existence of cuprophilic interactions. Complex 2 crystallizes with two independent molecules per asymmetric unit. Each copper atom is coordinated with three sulfur atoms of Detu and with one iodide ion in a tetrahedral arrangement.
