Bis(3-hydroxypyridine-κN)bis(3-nitrobenzoato-κO)zinc(II)

The title complex, [Zn(C7H4NO4)2(C5H5NO)2], has site symmetry 2. The ZnII ion is located on a crystallographic twofold rotation axis and assumes a distorted tetrahedral ZnN2O2 coordination geometry. Molecules are linked by an intermolecular O—H...O hydrogen bond and π–π stacking interactions between pyridine rings [centroid–centroid speparation 3.594 (1) Å].
