Hydrothermal synthesis and crystal structure of an infinite 1D ladderlike metal-organic compound: [Cu2(btec)(2,20-bipy)2]1 (btec ¼ 1,2,4,5-benzenetetracarboxylate)

A new metal-organic hybrid compound [Cu2(btec)(2,20-bipy)2]1 (btec ¼ 1,2,4,5-benzenetetracarboxylate) has been hydrothermally synthesized and characterized by elemental analyses, IR spectrum, TG analysis and single-crystal X-ray diffraction. Dark-blue crystals crystallizes in the monoclinic system, space group P2ð1Þ=n; a ¼ 7.2587(15) A° , b ¼ 12:396ð3Þ A° , c ¼ 14:428ð3Þ A° , b ¼ 103:87ð3Þ8; V ¼ 1260:4ð4Þ A3; Z ¼ 2; R1 ¼ 0:0553; wR2 ¼ 0:1746: The title compound exhibits a new infinite 1D ladderlike chain architecture constructed from the {Cu(2,20-bipy)}2þ moieties and btec ligands. Furthermore, the adjacent chains are stacked into a 3D supramolecular framework via p–p stacking interactions of bipy groups and intermolecular hydrogen bonding interactions. q 2003 Elsevier B.V.
