The title complex, C24H18Br2N4ZnO3, has been prepared and characterized by X- ray diffraction analysis. It crystallizes in the triclinic system, space group P1 with a = 0.89000(11), b = 1.22172(14), c = 1.31342(16) nm, α = 101.696(2), β = 103.519(2), γ = 110.744(2)o, V = 1.2329(3) nm3, Z = 2, Mr = 635.61, F(000) = 628, Dc = 1.712 g/cm3 and μ(MoKα) = 4.270 mm-1. The structure was refined to the final R = 0.0524 and wR = 0.1239 for 2763 observed reflections with I > 2σ(I). The X-ray crystal structure analysis revealed that the center zinc(II) is bonded with two oxygen and one nitrogen atoms from a tridentate ligand 3,5-dibromo-salicylaldehyde salicy- loylhydrazone (DBSHSH) and two nitrogen atoms from two solvent pyridine molecules to form a distorted five-coordinate trigonal bipyramid. The intramolecular hydrogen bonds in the crystal structure play an important role in the title complex’s thermostability.
