| 摘 要： | A novel coordination polymer of Cu II with flexible ligands,namely,Cu 3 (mal) 2 (di2-pyridlyktone) 2 ] (1,H 2 mal=maleic acid),was synthesized and characterized by single-crystal X-ray diffraction,thermogravimetric analyses,elemental analysis and IR spectroscopy.The structure indicates that the complex crystallizes in monoclinic,space group P2 1 /c with a=10.268(2),b=17.737(3),c=8.038(1),β=98.275(2)°,V=1448.6(4) 3,Z=2,D c=1.883 Mg·m-3,μ=2.260 mm-1,F(000)=826,and the final R=0.0321 and wR=0.0820.In 1,three Cu II centers (Cu(1),Cu(2),Cu(1A)) are bridged by two uncommon μ 3-bridging H 2 mal ligands,furnishing a centrosymmetric trimetallic unit.Via further Cu-O COO coordination interactions,extention of these trimetallic units in two directions gives rise to an infinite corrugated 2D layer.In addition,thermal stability and electrochemistry of 1 were studied.

| Abstract: | A novel coordination polymer of Cun with flexible ligands,namely,Cu3(mal)2(di-2-pyridlyktone)2] (1,H2mal = maleie acid),was synthesized and characterized by single-crystal X-ray diffraction,thermogravimetric analyses,elemental analysis and IR spectroscopy. The structure indicates that the complex crystallizes in monoclinic,space group P21/c with a = 10.268(2),b 17.737(3),c = 8.038(1) (A°),β = 98.275(2)°,V = 1448.6(4)(A°)3,Z = 2,Dc = 1.883 Mg·m-3,μ = 2.260=mm-1,F(000) = 826,and the final R = 0.0321 and wR = 0.0820. In 1,three CuⅡ centers (Cu(1),Cu(2),Cu(1A)) are bridged by two uncommon μ3-bfidging H2mal ligands,furnishing a centrosymmetric trimetallie unit. Via further Cu-OCOO- coordination interactions,extention of these trimetallic units in two directions gives rise to an infinite corrugated 2D layer. In addition,thermal stability and electrochemistry of 1 were studied. |
