The crystal of ZnL2 was determined by X-ray diffraction. It crystallizes in the Monoclinic system, space group C2/c with a=2.269 1(3), b=0.918 2(1), c=1.239 5(2) nm, β=117.89(2), Z=4, R1=0.049 4, wR2=0.138 2. The complexes were found to be active against Staphylococcus aureus and Eschierichia Coli. CCDC: 249474.展开更多

The structure of the mixed complex was characterized by elemental analysis, IR, 1H NMR and thermal analysis. The crystal structure of the complex was also determined by X-ray single crystal diffraction. Its crystal belongs to trigonal system with space group P31, a=1.109 67(18) nm, b=1.109 67(18) nm, c=1.236 8(4) nm, V=1.318 9(5) nm3; Dc=1.616 g·cm-3; Z=3; F(000)=666; μ=1.553 mm-1. CCDC: 253908.展开更多

The structure of the coordination polymer was confirmed by IR, 1H NMR, elemental analysis and thermal analysis. The crystal structure of the coordination polymer was also determined by X-ray single crystal diffraction. The crystal belongs to monoclinic system with space group P21/m, and crystallographic data of the coordination polymer are: a= 0.863 1(4) nm, b=0.717 7(3) nm, c=1.116 4(5) nm, α=γ=90°, β=107.542(6)°, V=0.659 4(5) nm3; Dc=2.037 g·cm-3; Z=2; F(000)=400; μ=1.969 mm-1. Zinc(Ⅱ) atom lies at the center of an octahedron formed by the coordination of zinc atom and six O atoms which come from four different trifluoroacetate ions and two different 3-hydroxypyridine molecules where each trifluoroacetate ion and 3-hydroxypyridine are coordinated to two different zinc ions to form coordination polymer.
