【Abstract】 A Cu(Ⅱ) complex [Cu(phen)2Br](H3BTEC)(1,phen=1,10-phenanthroline,H4BTEC=1,2,4,5-benzenetetracarboxylic acid) was synthesized,and charactered by elemental analysis,IR spectra,UV-Vis spectra,single crystal X-ray diffraction,TG analysis and electrochemical property.The complex crystallizes in triclinic,space group P1 with a=0.971 00(19) nm,b=1.212 0(2) nm,c=1.4290(3) nm;α=102.21(3)°,β=99.57(3)°,γ=107.64(3)°,V=1.51774(7) nm3,Z=2,C34H21BrCuN4O8,Mr=757,Dc=1.656 g·cm-3,μ=2.098 mm-1,F(000)=762,S=1.059,the final R=0.044 9 and wR=0.086 4 for 4 657 observed reflections with I>2σ(I).Two types of one-dimensional chains are demonstrated in the structure.On one hand,the C-H…Br hydrogen bonds and Br…π stacking interactions connect the [Cu(phen)2Br]+ cations into one-dimensional chains;on the other hand,the O-H…O hydrogen bonds aggregate the mono-deprotonated anions into one-dimensional double-layer chains.The two different kinds of chains are further packed into a three-dimensional framework with C-H…O contacts.更多还原
