The single crystal structure has been determined by X-ray diffraction analysis. The crystal belongs to monoclinic system, space group C2/c with cell constants, a=2.273 6(4) nm, b=0.592 12(9) nm, c=1.828 1(3) nm, β=109.735(5)°, V=2.316 4(7) nm3, Z=4, μ=1.164 mm-1, Dc=1.595 g·cm-3, F(000)=1 140, R=0.048 6, wR=0.101 6. In the compound copper(II) atom is four-coordinated with two nitrogen atoms from amide and two oxygen atoms from keto group. Their biological activities have been measused. The results show that the anti-bacterial activity of the coordination compound is much better that of the ligand. CCDC: 272938.展开更多

It crystallizes in monoclinic space group C2/c with a=2.9590(2) nm, b=1.4664(10) nm, c=1.764 3(12) nm, β=105.593(11)°, V=7.372(9) nm3, Dc=1.489 g·cm-3, Z=8, F(000)=3 416, R1=0.043 6, wR2= 0.1519. The crystal structure shows that the copper atom is coordinated with four nitrogen atoms from two phens and one oxygen atom from one terephthalic acid, forming a distorted square-pyramid coordination geometry. The cyclic voltametric behavior of the complex is also reported. CCDC: 277047.展开更多

Crystal data： monoclinic, space group C2/c with a = 2.2927（4）, b = 1.01248（18）, c = 1.05061（18） nm, β = 111.188（3）°, V= 2.274（7） nm^3, Dc = 1.513 g/cm^3, Z = 4, F（000） = 1060,μ = 1.007mm^-1, R = 0.0320 and ωR = 0.0781. The crystal structural analysis shows that the copper atom is coordinated with four oxygen atoms from two α-furacrylic acids and two nitrogen atoms from 1,10-phenanthroline, giving a distorted octahedral coordination geometry. The result of electrochemical analysis shows that the electron transfer in the electrode reaction is quasi-reversible.展开更多
