Synthesis and Crystal Structure of Two One—dimensional Chain Copper Complexes [Cu（TTA）2（4,4‘’—azpy）] and [Cu（TTA）2（3,3‘’—azpy）

Two copper complexes[Cu(TTA)2(4,4''''''''-azpy)](1)and [Cu-(TTA)2(3,3''-azpy)](2)(HTTA=1,1-trifluoro-3-(2-thenoyl)-acetone,4,4''azpy=4,4''-azobispyridine,3,3''-azpy=3,3''''''''-azo-bispyridine)were synthesized and characterized.The crystal structures were determined by X-ray diffraction analysis.The crystal 1 belongs to triclinic with space group p1^-,a=0.8515(2)nm,b=0.9259(2)nm,c=0.9468(2)nm,α=66.126(9)°，β=79.667(9)°，γ=90.13(1)°，z=1，V=0.6692(2）nm^3,Dc=3.425g/cm^3,μ=2.113mm^-1,F(000)=694,R1=0.594,wR2=0.1499,The crystal 2 belongs to monoclinic with space group P21/C,a=1.0661(2)nm,b=1.4296(3)nm,c=1.0041(3)nm,β=144.50(3)°,V=1.3926(5)nm^3,Z=2,Dc=1.646g/cm^3,μ=1.015mm^-1,F(000)=694,R1=0.0535,wR2=0.1113.In the crystals of complexes 1 and 2,the copper atoms have distorted octahedral symmetry.The two compounds possess very similar one-dimensional linear chains linked through the rodlike4,4''-azpy ligands or 3,3''-azpy ligands.
