The title mononuclear [Cu(sq)(phen)2]·3H2O complex [sq is squarate (C4O4) and phen is 1,10-phenanthroline (C12H8N2)] has been synthesized and the structure consists of a neutral mononuclear [Cu(sq)(phen)2] unit and three solvate water molecules. The CuII ion has distorted square-pyramidal coordination geometry, comprised of one carboxylate O atom from a monodentate squarate ligand and four N atoms from two chelating phen ligands. An extensive three-dimensional network of OW—H…O/OW hydrogen bonds, face-to-face – interactions between the 1,10-phenanthroline aromatic rings and a weak –ring interaction are responsible for crystal stabilization.
