Bis[μ-2,2′-dimethyl-1,1′-(3-oxapentane-1,5-di­yl)di-1H-benzimidazole-κ(2) N (3):N (3′)]bis­[bis­(4-meth­oxy­benzoato)-κO;κ(2) O,O′-cobalt(II)]

The complete mol­ecule of the title complex, [Co(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The Co(II) ion is penta­coordinated by three O atoms from two 4-meth­oxy­benzoate anions (one bidentate and one monodentate) and two N atoms from two 2,2′-bis­(2-methyl-1H-benzimidazole)­ether ligands. This results in a very distorted trigonal–bipyramidal geometry for the metal ion, with both N atoms in equatorial sites. The dihedral angle between the benzimidazole ring systems in the ligand is 60.04 (8)°. The configuration of the mol­ecule is supported by intra­molecular C—H⋯O hydrogen bonds.
