Chloridobis(1,10-phenanthroline-κ²N,N′)copper(II) iodide monohydrate

Abstract

The asymmetric unit of the title compound, [CuCl(C12H8N2)2]I·H2O, consists of a [CuCl(phen)2]+ cation (phen = l,10‐phenanthroline), an iodide anion and a water mol­ecule of crystallization. The coordination geometry around the CuII atom is distorted trigonal‐bipyramidal. The crystal packing is stabilized by inter­molecular π–π stacking inter­actions and C—H⋯O, O—H⋯Cl and O—H⋯I hydrogen bonds.

Stabilization of CuII–I Bonds Using 2‐Benzoylpyridine Thiosemicarbazones – Synthesis, Structure, Spectroscopy, Fluo­rescence, and Cyclic Voltammetry

“…Generally, iodide ions appear outside the coordination spheres of the various copper(II) complexes that have been reported previously. [1][2][3][4] However, there are a few reports of the formation of Cu II -I bonds, but nitrogen donor atoms contribute to the stabilization of molecular fluorescence, cyclic voltammetry, and single-crystal X-ray crystallography. The thio ligands coordinate as monoanionic N,N,S donors in 1-9.…”

“…In a typical reaction, copper(I) iodide with HL 1 in an acetonitrile/chloroform mixture (2:1 v/v) in the presence of PPh 3 (1 or 2 mol) formed the iodido-bridged dimeric complex [Cu 2 (μ-I) 2 2 ], [16] unlike the mononuclear complex [Cu I I(HL 1 )(PPh 3 ) 2 ] formed in acetonitrile. [14] Similarly, the mononuclear complex [ 4 ]} n formed in an acetonitrile/chloroform mixture. [17] Scheme 1.…”
