| Abstract: The complex [Cu2(nta)(Phen)3]NO3·6H2O has been synthesized in CH3OH/H2O solution with H3nta, Phen and copper(Ⅱ), where H3nta=nitriloriacetic acid and Phen=1,10-phenanthroline. The crystal structure of the complex has been determined by X-ray diffraction single crystal structure analysis. The crystal belong to monoclinic system, space group P21/c. The cell parameters are: a=1.251 05(9) nm, b=1.559 62(1) nm, c=2.249 70(2) nm, β=97.719 0(1)°, and V=4.349 8(5) nm3, Z=4, μ(Mo Kα)=10.59 cm-1, F(000)=2 112, R1=0.040 0, wR2=0.108 3 [I>2σ(I)]. The two copper atoms locate in a distorted coordination octahedron and a distorted coordination trigonal bipyramid, respectivety. Three-dimensional coordination network is formed through intermolecular hydrogen bonds of O-H…O and the π-π packing action between phenanthrolines .The results of TG analysis show the title complex was stable under 194 ℃. CCDC: 654192. | |
