摘 要: | A novel imide nickel complex Ni(CH3CONCOCH3)2·2(H2O)] was synthesized by the solvothermal reaction of nickel acetate tetrahydrate and acetonitrile.What amazed us is that acetonitrile had changed into acetyl imide in enol form during the formation process of the title complex.The complex was characterized by elemental analysis,IR spectrum and X-ray single-crystal diffraction analysis.It crystallizes in the orthorhombic system,space group Pbca with a = 7.4503(7),b = 13.1089(12),c = 14.1303(14),V = 1380.0(2)3,Dc = 1.420 g/cm3,Mr = 294.94,Z = 4,F(000) = 616,μ = 1.422 mm-1,the final R = 0.0487 and wR = 0.1482.The four-coordinated nickel(II) center is surrounded by 4O atoms from two imide ligands and has a distorted square planar geometry.The complex is connected to form a supramolecule with an infinite three-dimensional network through intramolecular and intermolecular hydrogen bonds.Antimicrobial activity was investigated by agar diffusion method,and the result showed that the complex was active against coli bacillus,staphylococcus aureus and bacillus subtilis.The thermal stability of the title complex was also studied by TG-DTA method.
