Abstract: | The synthesis, crystal structure, properties, and thermoanal. of mer-NiL(py)3 (H2L = o-vanillideneglycine) were reported. The complex is monoclinic space group C2/c, a 3.3549(6), b 1.1396(4), c 1.4555(5) nm, b 113.96(3)? Z = 8, R = 0.076, Rw = 0.089. The kinetics of thermal decomposition of the complex was studied also under nonisothermal condition by TG, DTG curves. The mechanism is three-dimension diffusion, 3D (sphere symmetry). The kinetic equation is expressed as: da/dt = Ae-E/RT.3/2.(1-a)2/3.[1-(1-a)1/3]-1. |
