Diaqua-[N-(5-nitro-2-oxidobenzyl-idene)glycinato]copper(II) dihydrate.

In the title complex, [Cu(C(9)H(6)N(2)O(5))(H(2)O)(2)]·2H(2)O, the Cu(II) atom has a square-pyramidal coordination environment with a tridentate N-(5-nitro-2-oxidobenzyl-idene)glycinate Schiff base ligand and a water mol-ecule in the basal plane. The apical site is occupied by an O atom from another coordinated water mol-ecule. The crystal structure is stabilized by O-H⋯O hydrogen bonds, building a two-dimensional network parallel to (100).
