Abstract

The title compound, dibromo(3-hydroxy-5-hydroxymethyl-2-methyl-4-pyridinecarboxaldehyde semicarbazone-kappa(3)N(1),O(3),O(3'))copper(II), [CuBr(2)(C(9)H(12)N(4)O(3))], consists of discrete complex units with the tridentate pyridoxal semicarbazone ligand as a zwitterion in an almost planar configuration. The Cu(II) ions are in a distorted square-pyramidal coordination, with the equatorial Br atom at a distance of 2.4017 (6) A and the apical Br atom at a distance of 2.6860 (6) A.
