Crystal structure of chlorido-[1-(4-nitro-phen-yl)thio-urea-κ S]bis-(tri-phenyl-phosphane-κ P)copper(I)

Abstract

The mononuclear mixed-ligand title complex, [CuCl(C₇H₇N₃O₂S)(C₁₈H₁₅P)₂], displays a distorted tetra-hedral coordination sphere around the Cu^I atom, with two P atoms from two tri-phenyl-phosphane mol-ecules, one terminal S atom from a 1-(4-nitro-phen-yl)thio-urea mol-ecule and a chloride ion as ligands. An intra-molecular N-H⋯Cl hydrogen bond stabilizes the mol-ecular conformation [graph-set motif R₂²(6)]. In the crystal, further N-H⋯Cl hydrogen bonds connect individual mol-ecules into zigzag chains parallel to [001]. The chains are linked by weak C-H⋯O hydrogen-bonding inter-actions into a three-dimensional network.

Keywords: N—H⋯Cl hydrogen bonding; crystal structure; intra- and inter­molecular hydrogen bonding.
