title: Synthesis and spectroscopic characterization of magnesium oxalate nano-crystals.
abstract: Synthesis of MgC92)O(4)⋅2H(2)O nano particles was carried out by thermal double decomposition of solutions of oxalic acid dihydrate (C(2)H(2)O(4)⋅2H(2)O) and Mg(OAc)(2)⋅(40H(2)O employing CATA-2R microwave reactor. Structural elucidation was carried out by employing X-ray diffraction (XRD), particle size and shape were studied by transmission electron microscopy (TEM) and nature of bonding was investigated by optical absorption and near-infrared (NIR) spectral studies. The powder resulting from this method is pure and possesses distorted rhombic octahedral structure. The synthesized nano rod is 80 nm in diameter and 549 nm in length.
