| Abstract: | Methyl,dimethyl and trimethyl ammonium tetrachloronickelates were prepared by solid state reactions of methyl;dimethyl;trimethyl amine hydrochlorides with anhydrous nickel chloride at room temperature for the first time. Near IR,IR,visible spectra and DSC were used to study products. The effects of number of methyl group in substituted ammonium on phase transition temperature were investigated and enthalpy changes of phase transition were calculated . |
