摘要
A new copper! coordination polymer, Cu(p-BDOA)(2,2′-bipy)·H2On (p-BDOA2-=benzene-1,4-dioxy- acetate dianion; 2,2′-bipy=2,2′-bipyridine) has been synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. The Crystal crystallizes in orthorhombic system, the space group is P212121, with the unit cell parameters a=0.698 4(1) nm, b=1.559 7(3) nm, c=1.750 6(4) nm and V=1.906 8(7) nm3, Mr= 461.91, Z=4, R=0.0575, wR=0.0783. Each copper! atom is six-coordinated and displays a distorted square pyramidal geometry with a one-capped base by one very long semicoordinate Cu-O(carboxylate) bond. Adjacent Cu! ions are bridged by carboxylate groups, resulting in a one-dimensional helical chain. The adjacent Cu…Cu distance within the polymeric chain is 1.3484 nm. Furthermore, such chains are linked through hydrogen bonds and π-πstacking interactions to form supramolecular network. CCDC: 219234.

Each copper（Ⅱ） atom is six-coordinated and displays a distorted square pyramidal geometry with a one-capped base by one very long semicoordinate Cu-O（carboxylate） bond. Adjacent Cu（Ⅱ） ions are bridged by carboxylate groups, resulting in a one-dimensional helical chain. The adjacent Cu…Cu distance within the polymeric chain is 1.348 4 nm.
