[N'-(4-Methoxy-2-oxidobenzylidene)4-nitrobenzohydrazidato-[kappa]3O,N,O'](pyridine-[kappa]N)copper(II)

Abstract top

The pyridine-coordinated CuII atom in the title Schiff base complex, [Cu(C15H11N3O5)(C5H5N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.

Related literature top

For the pyridine adducts of copper derivatives of similar ligands, see: Ali et al. (2004); Chen & Liu (2004); Das & Pal (2005); Fariati et al. (2002); Lu & Liu (2005); Lu et al. (2003).

Experimental top

N'-2-Hydroxy-3-methoxybenzylidene)-nitrobenzohydrazide (0.30 g, 1 mmol) and copper acetate (0.20 g, 1 mmol) were heated in a ethanol (50 ml) for 2 hours. The solvent was removed and the resulting compound recrystallized from pyridine.

Refinement top

Hydrogen atoms were placed at calculated positions (Caromatic–H 0.95 Å, Cmethyl–H 0.98 Å) and were treated as riding on their parent carbon atoms, with U(H) set to 1.2Ueq(Caromatic) or 1.5Ueq(Cmethyl).
