Aqua­[1-(4-carb­oxy­phen­yl)-1H-imidazole-κN (3)](pyridine-2,6-dicarboxyl­ato-κ(3) O (2),N,O (6))copper(II) monohydrate

In the title complex, [Cu(C(7)H(3)NO(4))(C(10)H(8)N(2)O(2))(H(2)O)]·H(2)O, the Cu(II) ion is in a slightly distorted square-pyramidal geometry. Two carboxyl­ate O atoms and one pyridine N atom from a pyridine-2,6-dicarboxyl­ate ligand chelate the Cu(II) ion, forming two stable five-membered metalla rings. One imidazole N atom from a 1-(4-carb­oxy­phen­yl)imidazole ligand and one water mol­ecule complete the five-coordination. O—H⋯O hydrogen bonds involving the coordinated water mol­ecules and carboxyl­ate groups link the complex mol­ecules into chain-containing dinuclear macrocycles. O—H⋯O hydrogen bonds involving the uncoordinated water mol­ecules link the chains into a layer extending parallel to (10[Image: see text]).
