Abstract
Mass spectral and thermal studies by TG analysis of Ni[S 2CN(COR')R] 2 complexes (R = Me, i-Bu, Ph, Bz; R' = Me, Ph) in a dynamic nitrogen atmosphere have been carried out to determine their modes of decomposition. Fragmentation patterns are given and possible mechanisms are discussed. All complexes show similar TG profiles. Mass loss considerations at the main decomposition steps indicate conversion of the nickel(II) amide N-carbo-dithioates to sulphides. Reaction orders were estimated by employing the Freeman-Carroll equation, and a kinetic analysis of TG data was performed using the Coats-Redfern equation to determine the apparent activation energies and the pre-exponential factor of the Arrhenius equation.
