In the title compound, [CuCl(C6H6)N4)(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) A, 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) A. Including the long coordination bonds, the geometries around the Cu atoms in the cation and anion are square-pyramidal and distorted octahedral, respectively.
