Crystal structure of poly[[μ-1,1′-(butane-1,4-diyl)bis(1H-benzimidazole)-κ2N3:N3′]{μ-4,4′-[1,4-phenylenebis(oxy)]dibenzoato-κ4O,O′:O′′,O′′′}cobalt(II)]

In the title compound, [Co(C20H12O6)(C18H18N4)]n, the CoII atom, located on a twofold rotation axis, is hexacoordinated to four O from two bis-bidentate 4,4′-[phenylenebis(oxy)]dibenzoate (L) ligands and two N atoms from two 1,1′-(butane-1,4-diyl)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).
