Crystal structure of poly[[{μ2-1,4-bis[(1H-imid-azol-1-yl)methyl]benzene}[μ6-5-(4-carboxylatophenoxy)isophthalato]-μ3-hydroxido-dicobalt(II)] 0.25-hydrate].

ABSTRACT: The title coordination polymer, {[Co2(C15H7O7)(OH)(C14H14N4)]·0.25H2O} n , was synthesized under hydro-thermal conditions. The asymmetric unit contains two Co(2+) ions, one L (3-) anion originating from 5-(4-carb-oxy-phen-oxy)isophthalic acid (H3 L), one OH(-) ligand, one 1,4-bis-[(1H-imidazol-l-yl)meth-yl]benzene (bix) ligand and one disordered lattice water mol-ecule (occupancy 0.25). The two Co(2+) ions have different environments. One has an octa-hedral O4N2 coordin-ation sphere, defined by four O atoms from three carboxyl-ate groups and one OH(-) ligand, and two N atoms from two symmetry-related bix ligands. The other has a trigonal-bipyramidal O5 coordination sphere resulting from three carboxyl-ate groups and two OH(-) ligands. The dihedral angles between the two benzene rings in th
