Solid State Synthesis of Triethanolammonium Tetrachloronickelate and Its Thermochromism
Abstract:
Triethanolammonium tetrachloronickelate was synhesized by a solid state reaction of triethanolamine hydrochloride with anhydrous nickel chloride. The compound undergoes a reversible thermochromism phase transition at ca.152℃. UV-visible, near-IR, IR spectra and elemental analysis results confirmed the structure of the product. It was deduced that thermochromism of the product is caused by the structural phase transition of the complex ion, NiCl42-. The enthalpy change of phase transition for the product was 61.0 kJ/mol determinated by DSC.
