Abstract

In the title compound, [V(C7H3NO4)O(C10H8N2)]C2H5OH, the VIV atom exhibits a distorted octahedral coordination environment formed by two pyridyl N atoms of 2,20-bipyridine (bpy), the vanadyl O atom, and two carboxylate O atoms and one pyridyl N atom of the tridentate pyridine-2,6-dicarboxylate (pydc2) ligand. The pyridyl N atom of the pydc2 anion and one pyridyl N atom of bpy occupy the axial positions. O— H  O hydrogen bonds involving the ethanol solvent molecule as donor and a carboxylate O atom as acceptor atoms, as well as C—H  O hydrogen bonds, together with – stacking interactions between adjacent aromatic rings (average centroid–centroid distance = 3.577 A ° ), seem to be effective in the stabilization of the crystal packing, resulting in the formation of a three-dimensional structure.
