Synthesis of a metal-dicarboxylate hybrid with three dimensional Na-O-Cu connectivity: structure, magnetic property and controlled solid state thermolysis leading to CuO nanorod

A one-pot reaction of CuCl2 · 2H2O and disodium malonate leads to a novel three dimensional heterometallic inorganic-organic hybrid framework where the malonate functions as a heptadentate ligand. Low temperature magnetic study reveals that the compound is weak ferromagnetically coupled. On heating this compound transforms into CuO nanorods with average diameters of ca. 40-200 nm and lengths up to 13 μm.
