ABSTRACT: The title compound, {[Co(3)(C(6)H(4)NO(2))(2)(C(8)H(3)NO(6))(2)(H(2)O)(2)]·4H(2)O}(n), exhibits a two-dimensional layer-like structure in which the Co(II) ions exhibit two kinds of coordination geometries. One nearly octa-hedral Co(II) ion with crystallographic inversion symmetry is coordinated to six carboxyl-ate O atoms from four bridging 5-nitro-isophthalate (NIPH) ligands and two isonicotinate (IN) anions, while the other type of Co(II) ion binds with one N atom and one carboxyl-ate O atom from two IN anions, two carboxyl-ate O atoms from two different NIPH anions and one ligated water mol-ecule, displaying a distorted square-pyramidal coordination geometry. Three adjacent Co(II) ions are bridged by six carboxyl-ate groups from four NIPH ligands and two IN anions to form a linear trinu
