Bis[μ-2,2′-dimethyl-1,1′-(3-oxapentane-1,5-diyl)di-1H-benzimidazole-κ2 N 3:N 3′]bis[bis(4-methoxybenzoato)-κO;κ2 O,O′-cobalt(II)]

چکیده
The complete mol-ecule 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 penta-coordinated by three O atoms from two 4-meth-oxy-benzoate 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 mol-ecule is supported by intra-molecular C-H⋯O hydrogen bonds.
