Abstract:
In the binuclear title complex, [Er(2)(C(13)H(9)N(3)O(2))(2)Cl(2)(CH(3)OH)(2)], the entire mol-ecule is generated by the application of inversion symmetry. Each Er(III) ion is seven-coordinated by two O atoms and one N atom from one N-(2-oxidobenzyl-idene)pyridine-2-carbohydrazidate (L(2-)) ligand, one O atom and one N atom from the symmetry-related L(2-) ligand, one O atom of a methanol mol-ecule and one chloride anion. The coordination geometry is based on a pseudo-penta-gonal bipyramid. Linear supra-molecular chains along [010] are formed in the crystal packing through O-H⋯Cl hydrogen bonds.
