Abstract

The title compound, [CdBr(2)(C(13)H(12)N(4)O)], was obtained from the reaction of Cd(NO(3))(2)·4H(2)O with meth-yl(pyridin-2-yl)methanone picolinoylhydrazone and sodium bromide. The Cd(2+) cation is ligated by one O atom and two N atoms of the tridentate ligand and two bromide anions, forming a Br(2)CdN(2)O polyhedron with a distorted trigonal-bipyramidal coordination geometry. In the crystal, non-classical C-H⋯Br hydrogen bonds are observed. In addition, π-π stacking inter-actions [centroid-centroid distance = 3.7455 (19) Å] contribute to the stabilization of the crystal structure.
