Bis(μ‐3‐carboxyl­ato­phenoxy­acetato)­bis­[(1H‐imidazole)copper(II)] dihydrate

In the title centrosymmetric dinuclear complex, [Cu2(3‐CPOA)2(C3H4N2)4]·2H2O (3‐CPOA2− is the 3‐carboxyl­ato­phenoxy­acetate dianion, C9H6O5), each CuII ion is coordin­ated by three carboxyl O atoms, one ether O atom from two 3–CPOA2− groups and two N atoms from two imidazole co‐ligands, displaying an elongated square‐pyramidal coordin­ation geometry with a based capped by one very long semicoordinate Cu—Ocarboxyl bond [2.8191 (15) Å]. The two CuII ions are bridged by 3–CPOA2− ligands, generating a macrocyclic ring motif, with a Cu⋯Cu separation of 6.879 (3) Å. The dinuclear motifs are further linked into a two‐dimensional supramolecular network via hydrogen‐bonding interactions.
