Catena-Poly[[diaqua-bis-[2-(3-oxo-1,3-di-hydro-2-benzofuran-1-yl)acetato-?O]cobalt(II)]-?-1,2-bis-(pyridin-4-yl)ethane-?(2)N:N'].


ABSTRACT: In the title complex, [Co(C(10)H(7)O(4))(2)(C(12)H(12)N(2))(H(2)O)(2)](n), the Co(II) ion is located on a crystallographic centre of symmetry and is six-coordinated by two N atoms from two 1,2-bis-(4-pyrid-yl)ethane ligands, two carboxylate O atoms from two 1,3-dihydro-3-oxo-1-isobenzofuran-acetate ligands and two terminal water ligands. The 1,2-bis(4-pyrid-yl)ethane ligands act as bidentate ligands, and bridge the Co(II) ions into infinite chains extending parallel to [010]. In these chains, there are intra-mol-ecular O-H?O hydrogen bonding between the coordination water mol-ecules and carboxyl-ate groups. Inter-mol-ecular O-H?O hydrogen bonding between the adjacent chains and ??? stacking inter-actions result in the formation of a three-dimensional supra-molecular network.
