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

On the basis of preceding work, we have synthesized eight mixed ligand complexes of Cu? with Schiff base derived from β diketone, salicylaldehyde and some aminoacid. Lignads of N,N′ (benzoyl acetonyl) phenylene diamine, N,N′ (diacetonyl) phenylene diamine, salicylaldehyde semicarbazone, benzoyl acetone semicarbazone, sodium salicylaldehyde histidine, potassium salicylaldehyde tyrosine, potassium benzoyl acetonyl histidine and potassium diacetonyl tyrosine are used respectively. Those have been characterized by elemental analyses, molar conductances, infrared spectra, UV spectra and TG DTA analysis. A study preliminarily on the structures and characters for these compounds have been carried out in this article, and their bioactivity of restraining function to escherichia coli has also been discussed. According to all the data, the formulas of [Cu(C16H14N2)Cl2],[Cu(C11H12N2)Cl2],[Cu(C8H9O2N3)Cl2],[Cu(C12H16O2N6)]Cl2,[Cu(C13H11O3N3)(H2O)]· 3H2O,[Cu(C16H13O4N)(H2O)]· 2H2O,[Cu(C20H23O7N3)], [Cu(C15H21O7N3)] are estimated.展开更多

The crystal structure was determined by X ray diffraction method and the chemical formula weight of the complex is 498.00. And the crystal structure belongs to orthorhombic system with space group Pbcn and cell parameters: a=31.072(4)?, b=12.8909(18)?, c=10.3478(14)?; V=4144.7(10)?3,Z=8,Dc=1.596Mg·m-3,μ=1.197mm-1 and F(000)=2048. The compound is an one dimensional chain complex of infinite length connecting with hydrogen bonds. The Cu? was coordinated by two oxygen atoms and three nitrogen while the O atoms of Ac groups did not coordinate. At the same time the Cu?formed a distorted tragonal cone. Besides the capacities of coordination to Cu? of atoms were discussed.展开更多
