2N,O]dinitratocopper(II)Abstract: In the crystal structure of the title compound, [Cu(NO3)2(C6H7NO)2], the copper(II) ion resides at an inversion centre and it has a 4 + 2 elongated ocatahedral coordination environment. The equatorial positions are occupied by two OH groups and two N atoms from a pair of neutral 2-(hydroxymethyl)pyridine ligands, while the two axial positions are weakly ligated by two nitrate O atoms. Adjacent mononuclear copper(II) complexes are further joined together by O-H
O hydrogen bonds to form a linear chain along the a axis.
