Abstract
New 3D complexes [Cd-3(nic)(4)(N-3)(2)(H2O)(2)](n) (1), [Cd( 2,5-dmpyz)(N3)(2)](n) (2) and [Zn(nic)(N-3)](n) (3) and 1D complex Zn(bipy)(N-3)(2)](n) (4), where (nic = nicotinate anion; 2,5-dmpyz = 2,5-dimethylpyrazine and bipy = 2,2 ' - bipyridyl), have been synthesized. The Kerr effect measurements on the solutions of these complexes in dimethyl sulfoxide as a common solvent allow the determination of the nonlinear molecular properties of these organic/inorganic polymers. Solutions in the concentration range from zero to 20mg/ml have been measured and the values and dynamics of the induced anisotropy have been discussed. Thermal properties and decomposition kinetics of the studied complexes are investigated. The kinetic parameters (E, A, Delta H, Delta S and Delta G) of all thermal decomposition stages have been calculated using the Coats-Redfern and other standard equations.
