title: catena-Poly[[tripyridine-nickel(II)]-μ-5-bromo-isophthalato].
abstract: The title compound, [Ni(C(8)H(3)BrO(4))(C(5)H(5)N)(3)], is the first structurally characterized complex with a transition metal coordinated by a 5-bromo-isophthalate anion. The Ni(II) ion is coordinated by three O atoms from the carboxyl-ate groups and three N atoms from three pyridine ligands in a distorted octa-hedral coordination geometry. The 5-bromo-isophthalate anion is planar within 0.057 (2) Å. The two carboxyl-ate groups of the ligand coordinate the Ni(II) ions in a chelating and monodentate mode, linking the metal atoms into infinite chains along the [010] direction. These chains are stacked together via strong π-π inter-actions between the pyridine rings [centroid-centroid distance 3.601 (4) Å], forming a three-dimensional motif.
