The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 1041.85. The crystal structure belongs to triclinic system with spacegroup and cell parameters: a=12.6470(10) , b=14. 123(2) , c=15.613(2);á=66.150(10)a=79.470(10)?=78.290(10)穖-3 and F(000)=1064. The final R:R1=0.0668, wR 2=0.1927; R(all data): R1=0.1133, wR2=0.2357. The Cu was coordinated by six nitrogen, at the same time the Cu formed a distorted octahedron, besides the angles and pl anes of this compound were discussed . The result of kinetics of the thermal dec omposition indicated that the first step of it is 2 series chemical reactions, t he function of machanism is f(a)=(1-a)2, and the activation energy is 144.64E/ kJ.

It is of monoclinic system, space group P21/c with a = 9.213(2), b = 17.479(4), c = 11.510(2) ? b = 100.32(3)o, V = 1823.7(6) 3, Z = 4, C17.5H16Cl2FeHgN2, Dc = 2.119 g/cm3, m = 9.497 mm-1, F(000) = 1100, R = 0.0436 and wR = 0.0987. The independent reflections are 3527, of which 3153 with I ≥ 2s(I) were observed. The compound contains a five-membered metallocycle. The mercury atom is bonded with the 2-position of substituted cyclopentadienyl ring (Cp), and coordinated weakly to the N atom of imino group. The pyridyl ring is almost perpendicular to the substituted Cp which is nearly coplanar with the metallocycle. The Hg(1)C(1) and Hg(1)Cl(1) bond lengths are 2.050(8) and 2.321(2) ? respectively.展开更多
