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.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.
