A new mononuclear Cd(II) complex CdL2I2 (L = 6-nitro-imidazo(1,2-a)pyridine) made up by a novel in situ reaction

ABSTRACTA novel in situ cyclocondensation reaction of anp (anp = 2-amino-5-nitropyridine) and ethanol into L (L = 6-nitro-imidazo(1,2-a)pyridine) under solvothermal conditions has been observed for the first time. Crystal structure of a metal complex, CdL2I2 (1), has been obtained. Complex 1 was synthesized from a solvothermal reaction of anp with CdI2 in anhydrous ethanol and water. Complex 1 crystallizes in orthorhombic space group Pnma with a = 13.662(9) A, b = 16.734(11) A, c = 8.767(5) A. The structure of 1 shows mononuclear units. Weak hydrogen bonds and π···π stacking intermolecular interactions assemble units to form a 3-D supramolecular network of 1.
