Aqua(6,6′-oxydipicolinato-κ2O,N,N′,O′)copper(II)

In the title complex, [Cu(C12H6N2O5)(H2O)], the Cu-II ion is in a slightly distorted square-pyramidal coordination environment with two N and two O atoms from a 6,6'-oxydipicolinate ligand occupying the basal plane and a water ligand in the apical site. The dihedral angle between the two pyridine rings is 5.51 (6)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O hydrogen bonds link molecules into a two-dimensional network. In addition, weak intermolecular C-H center dot center dot center dot O and C=O(lone pair)center dot center dot center dot pi(ring) interactions, with O center dot center dot center dot ring-centroid distances of 3.697 ( 4) and 3.094 ( 4) angstrom, provide additional stabilization.
