4-Methoxypyridine-(pyridine-2,6-dicarboxylato-N,O,O′) copper(II)

The synthesis and X-ray crystal structure Of [Cu(C7H3NO4)(C6H7NO)], [Cu(dipic)(4-MeO-Py)], (dipic=pyridine-2,6-dicarboxylate, 4-MeO-Py=4-methoxypyridine), is described. Molecules of [Cu(dipic)(4-MeO-Py)] are formed via coordination of the copper(II) cation to two nitrogen atoms, from the dipic and 4-MeO-Py ligands respectively, and to two oxygen atoms from the carboxylate groups of the dipic ligand. The molecules pack in a non-centrosymmetric manner, stacked eclipsed with respect to one another along the b-axis and aligned parallel in a head-to-tail motif. The title compound crystallizes in the orthorhombic space group, Pca2(1), with a=27.339(3) Angstrom, b=3.7130(4) Angstrom, c=11.6859(12) Angstrom, V=1186.2(2) Angstrom(3), and Z=4. The structure was solved by direct methods and refined by least-squares methods to a final R-factor of 0.0327 for 2648 independent reflections.
