title: Aqua[N-(2,5-dihydroxybenzyl)imino-diacetato]copper(II).
abstract: The title complex, [Cu(C(11)H(11)NO(6))(H(2)O)], contains a Cu(II) atom in a distorted square-pyramidal geometry. The metal centre is coordinated in the basal sites by one water mol-ecule and two carboxyl-ate O atoms and one N atom of the tetra-dentate ligand [Cu-O range, 1.9376 (11)-1.9541 (12), Cu-N, 1.9929 (12) Å] while the apical site is occupied by a hydro-quinone O donor atom [Cu-O, 2.3746 (12) Å]. Inter-molecular hydrogen bonding inter-actions involving both hydro-quinone hydr-oxy groups and the coordinated water as donors give a three-dimensional framework structure.
