title: Poly[[μ-1,4-bis-(1H-imidazol-4-yl)benzene-κN:N](μ-5-methyl-isophthalato-κO:O)cobalt(II)].
abstract: In the title coordination polymer, [Co(C(9)H(6)O(4))(C(12)H(10)N(4))](n), the Co(II) atom is four-coordinated by two O atoms from two different 5-methyl-isophthalate bivalent anions and two N atoms from two different 1,4-bis-(1H-imidazol-4-yl)benzene ligands, forming a four-coordinated tetra-hedral coordination geometry. Each 5-methyl-isophthalate ligand acts as a μ(2)-bridge, linking two Co(II) atoms and forming chains which are further linked by 1,4-bis-(1H-imidazol-4-yl)benzene ligands into a two-dimensional network parallel to ([Formula: see text]01). These planes are, in turn, linked by two inter-molecular N-H⋯O inter-actions, forming a three-dimensional structure. Weak C-H⋯O hydrogen bonds are also present in the structure.
