A novel helical copper complex:: catena-poly[[[aquacopper(II)]-μ-N-(3-carboxy-2-oxidobenzyl-idene-κO2)glycinato-κ3N,O′:O′] monohydrate]

In the polymeric title compound, {[Cu(C10H7NO5)(H2O)]H2O}(n), the Cu atom adopts a square-based pyramidal coordination involving a N,O,O'-tridentate glycine dianionic ligand, a water O atom and an apical bridging carboxylate O atom from an adjacent ligand. The title compound also adopts a carboxylate-bridged chain structure. The molecular chain propagates in a helical fashion along the b axis of the monoclinic unit cell. Neighbouring chains are linked together to form a three-dimensional network via hydrogen-bonding interactions between coordinated and uncoordinated water molecules and O atoms of the bridging carboxylate groups.
