title: Crystal structure of bis-[μ-1,2-bis-(di-phenyl-phosphan-yl)ethane-κ(2) P:P']bis[(N,N'-di-ethyl-thio-urea-κS)iodidocopper(I)].
abstract: The binuclear title complex, [Cu2I2(C26H24P2)2(C5H12N2S)2], lies about an inversion centre. The Cu(I) atom displays a distorted tetra-hedral coordination geometry defined by one S atom of an N,N'-di-ethyl-thio-urea ligand, two P atoms derived from two bridging 1,2-bis-(di-phenyl-phosphan-yl)ethane (dppe) ligands and one iodide ion. The dppe ligand bridges two symmetry-related Cu(I) ions, forming a 10-membered Cu2P4C4 ring. An intra-molecular N-H⋯I hydrogen bond is noted. In the crystal, N-H⋯I hydrogen bonds link complex mol-ecules into layers parallel to (-101).
