title: Crystal structure of poly[[μ-1,1'-(butane-1,4-di-yl)bis-(1H-benzimidazole)-κ(2) N (3):N (3')]{μ-4,4'-[1,4-phenyl-enebis(-oxy)]di-ben-zo-ato-κ(4) O,O':O'',O'''}cobalt(II)].
abstract: In the title compound, [Co(C20H12O6)(C18H18N4)] n , the Co(II) atom, located on a twofold rotation axis, is hexa-coordinated to four O from two bis-bidentate 4,4'-[phenyl-enebis(-oxy)]dibenzoate (L) ligands and two N atoms from two 1,1'-(butane-1,4-di-yl)bis-(1H-benzimidazole) (bbbm) ligands, forming a distorted octahedral cis-N2O4 coordination environment. Polymeric zigzag chains along [102] are built up by the bridging L ligands. These chains are additionally connected by the bbbm ligands to produce a two-dimensional coordination polymer parallel too (010).
