catena-Poly[[[4-bromo-2-(2-pyridylmethyliminomethyl)phenolato]zinc(II)]-mu-chloro].

The title complex, [Zn(C13H10BrN2O)Cl]n, is a chloride-bridged polynuclear zinc(II) compound. Each ZnII ion is five-coordinated in a square-pyramidal configuration, with one O and two N atoms of one Schiff base and one bridging Cl atom defining the basal plane, and another bridging Cl atom occupying the apical position. The novelty of the compound lies in the bridging by chlorine of two square-pyramidal Zn atoms, so that the bridging atom is apical for one Zn ion and basal for the other. This structural arrangement has not been observed before. The linked moieties form polymeric zigzag chains running along the a axis.
