In the title compound, [Cu(C~2~O~4~)(C~6~H~7~NO)~2~]~__n__~, the Cu^II^ atom is six-coordinated in a slightly deformed elongated octahedral arrangement and the 3-(hydroxymethyl)pyridine ligand, surprisingly, acts as a monodentate ligand coordinated only through the N atom of the pyridine ring. The o

In the title dimeric complex, [Cu~2~(C~2~O~4~)Cl~2~(C~12~H~8~N~2~)~2~], which lies on a crystallographic inversion center, the Cu^II^ ion is in a distorted trigonal–bipyramidal coordination geometry formed by two N atoms from a phen ligand, two O atoms from a bridging oxalate ligand and one Cl atom.
