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 hydrothermal reaction of NH 4VO 3, CoCl 2·6H 2O, o-phen and H 2O gave a novel two-dimensional layered polyoxovanadate, [Co(o-phen)]V 2O 6·H 2O, which was constructed from {V 2O 6} chains linked by Co(o-p...The hydrothermal reaction of NH 4VO 3, CoCl 2·6H 2O, o-phen and H 2O gave a novel two-dimensional layered polyoxovanadate, [Co(o-phen)]V 2O 6·H 2O, which was constructed from {V 2O 6} chains linked by Co(o-phen) complex fragments. [Co(o-phen)]V 2O 6·H 2O was characterized by IR, TG and single-crystal X-ray diffraction. It crystallizes in monoclinic space group P2(1)/c with a= 0.785 2(9) nm, b=2.118 3(2) nm, c=0.946 3(11) nm, β=112.827(2)°, V=0.145 1(3) nm3, D c=2.074 g/cm3, Z=4, R 1=0.038 8, wR 2=0.094 1.展开更多

The results showed that HL as a bidentate ligand coordinated with transition metal ions to form four-coordination complexes. The antibacterial activity was studied by using the filter scraps diffusion method, and the results indicated that the ligand and the complexes had a low bacteriostatic activity against S. Aureu, P. Aeruginosa and E. Coli. The low in vitro antitumor activity of the title complexes was also observed by using MTT method against KB, A2780, Bel7402 and HELF.展开更多
The synthesis of a Schiff base macrocyclic polyamine ligand and its five 1∶1 complexes with transition metals are reported.

All compounds were characterized by elemental analysis, IR, UV Vis, 1H NMR, 13 C NMR, MS and molar conductance measurements. The results showed that [CuL](ClO 4) 2 is a square planar complex. The others are octahedral complexes.展开更多
