Description
Summary:Two new copper complexes [(bipy)(pydc)Cu(&mu;-OCO-pydc)Cu(bipy)(H<sub>2</sub>O)].3.5H¬2O (<b>1</b>) and {[(&mu;<sub>2</sub>-C<sub>2</sub>O<sub>4</sub>)(2,2'-bipy)Cu].2H2O}<sub>n</sub> (<b>2</b>) (pydcH<sub>2</sub> = pyridine-2,6-dicarboxylilic acid, bipy = 2,2'-bipyridine) have been hydrothermally synthesized. Both complexes were characterized by IR spectroscopy, elemental analysis and single crystal X-ray diffraction studies. Complex <b>1</b> consists of two independent neutral molecules. In every moiety, metal ion center is in a distorted octahedral geometry. Coordination polymer <b>(2)</b> has been prepared from the reaction of bis-(cyclohexanone)-oxal-dihydrazone,2,2'-bipyridine and Cu(NO<sub>3</sub>)<sub>2</sub> in basic solution and under hydrothermal condition. The results showed that the bis-(cyclohexanone)-oxal-dihydrazone was converted to oxalate ion under heating and basic pH. Each metal ion center in <b>2</b> is in a distorted octahedral geometry and is coordinated by four oxygen atoms of two bridged oxalate ions and two nitrogen atoms of 2,2'-bipyridine molecules. In the crystal structure of <b>2</b>, some H-bonds and &pi;-&pi; interaction cause formation of a 3D network.
