Aqua(2,2'-bi-1H-imidazole)chloro-copper(II) chloro(iminodiacetato)-copper(II) monohydrate.

In the title compound, [CuCl(C₆H₆N₄)(H₂O)][Cu(C₄H₅NO4₎Cl]·H₂O, the Cu^II atom in the cation is coordinated by one Cl^- ion, two N atoms of the 2,2'-biimidazole ligand and one aqua ligand. Within the anion, the Cu^II atom is bonded to one Cl^- ion, and one N and two O atoms of the iminodiacetate ligand. Neighbouring cations and anions are connected to each other by Cu···Cl semi-coordination bonds of 2.830 (12) and 3.071 (12) baring;, forming a Cu₂Cl₂ rectangular unit. The dinuclear units further link into a polymeric chain along the a axis through Cu···O_aqua interactions of 2.725 (3) baring;. Including the long coordination bonds, the geometries around the Cu atoms in the cation and anion are square-pyramidal and distorted octahedral, respectively. [ABSTRACT FROM AUTHOR]
