Deskripsi

The complete molecule of the title complex, [Co2(C8H7O3)4(C20H22N4O)2], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The CoII 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.
