title: catena-Poly[[diaqua-bis(1H-imidazole-κN(3))cobalt(II)]-μ-2,3,5,6-tetra-chloro-tereph-thal-ato-κ(2)O(1):O(4)].
abstract: In the title compound, [Co(C(8)Cl(4)O(4))(C(3)H(4)N(2))(2)(H(2)O)(2)](n), the Co(II) ion displays a distorted octa-hedral coordination geometry with two O atoms from two monodentate tetra-chloro-terephthalate dianions, two N atoms from two imidazole mol-ecules and two O atoms from two water mol-ecules. The Co(II) ions are connected via the tetra-chloro-terephthalate dianions into a chain running along the crystallographic [110] direction. Adjacent chains are linked into a two-dimensional network arranged parallel to (010) by classical N-H⋯O and O-H⋯O hydrogen bonds.
