The crystal structure of the title complex has been determined by single crystal X ray diffraction techniques. The crystal belongs to monoclinic with space group P21/c. The cell parameters are: a=1.6362(9)nm, b=1.7140(9)nm, c=1.2255(7)nm, β=105.168(9)°, V=3.317(3)nm3, Z=8, Dc=1.525g·cm-3, μ(MoKα)=1.334mm-1, F(000)=1560. The structure wasrefined to final R1=0.0376, wR2=0.0909. The copper?ion lies in a distorted square planar environment composed of two oxygen atoms, one nitrogen atom of tridentate acyhydrazone Schiff base ligand and one nitrogen atom of the pyridine ligand.

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.
