Abstract
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)center dot(CH(3)CN)(0.5) (1) and [Cu(Detu)(3)I] (2), respectively. In compound 1 each copper atom is coordinated with one sulfur atom of Detu and with one chloride ion forming a centro-symmetric trinuclear core (Cu(3)S(3)Cl(3)) that exhibits a Cu-Cu separation of 2.7383(5) angstrom 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.
