In the noncentrosymmetric title compound, [Cu(C4H5NO4)-(C6H12N4)(H2O)] or [Cu(IDA)(HMTA)(H2O)], where IDA is iminodiacetate and HMTA is hexamethylenetetramine, the asymmetric unit consists of a whole mononuclear neutral molecule, where the Cu II cation is coordinated by two carboxylate O atoms and one N atom from the IDA ligand, by one N atom from the HMTA ligand and by the O atom of the coordinated water molecule, giving rise to a CuN2O3 distorted square-pyramidal coordination geometry. The IDA and HTMA ligands adopt terminal tri- and monocoordinated modes, respectively. All adjacent molecules within the ac plane are connected to each other via two pairs of O-H center dot center dot center dot O and one N-H center dot center dot center dot O hydrogen bond, forming a (4,4) supra-molecular two-diensional network. In the unit cell, these layers stack alternately in an ... ABABAB ... sequence along the b axis. The optical absorption properties of this compound have been studied on powder samples, which had previously been examined by powder X-ray diffraction.
