Abstract

The title compound, [CdBr2(C13H12N4O)],was obtained from the reaction of Cd(NO3)(2)center dot 4H(2)O with methyl(pyridin-2-yl)-methanone picolinoylhydrazone and sodium bromide. The Cd2+ cation is ligated by one O atom and two N atoms of the tridentate ligand and two bromide anions, forming a Br2CdN2O polyhedron with a distorted trigonal-bipyramidal coordination geometry. In the crystal, non-classical C-H center dot center dot center dot Br hydrogen bonds are observed. In addition, pi-pi stacking interactions [centroid-centroid distance = 3.7455 (19) angstrom] contribute to the stabilization of the crystal structure.
