The crystal belongs to triclinic system, space group P1 with cell constant, a=1.230 69(10) nm, b=1.329 18(11) nm, c=1.330 56(11) nm, α=113.702(2)°, β=91.590(2)°, γ=100.846(2)°, V=1.944 4(3) nm3, Z=2, μ=0.662 mm-1, Dc=1.482 g·cm-3, F(000)=896, Rint=0.048 7. The crystal structure shows an anionic didentate ligand O and N donors in this work. The cobalt(Ⅲ) atom is hexacoordinated with oxygen atom from keto group and nitrogen atom from amide to form a cobalt atom for the core octahedral structure. CCDC: 748882.展开更多

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
