Abstract

The binuclear title complex, [Cu2I2(C26H24P2)2(C5H12N2S)2], lies about an inversion centre. The CuI atom displays a distorted tetrahedral coordination geometry defined by one S atom of an N,N′-diethylthiourea ligand, two P atoms derived from two bridging 1,2-bis(diphenylphosphanyl)ethane (dppe) ligands and one iodide ion. The dppe ligand bridges two symmetry-related CuI ions, forming a 10-membered Cu2P4C4 ring. An intramolecular N—H⋯I hydrogen bond is noted. In the crystal, N—H⋯I hydrogen bonds link complex molecules into layers parallel to (-101).
