• The solubility of hexaamminenickel(II) complexes in aqueous ammonia solution (0 to 37 g-free NH<SUB>3</SUB>/100g-solv.) was investigated at temperatures 0–55 °C. It rapidly decreases with increase in free ammonia concentration but increases with rise in temperature. Hexaamminenickel(II) carbonate, sulfate, and chloride are slightly soluble at ammonia concentration above 30 g-free NH<SUB>3</SUB>/100 g-solv., but nitrate is considerably soluble even at ammonia concentration of 35 g-free NH<SUB>3</SUB>/100 g solv. The thermal decomposition of ammine complexes of nickel(II) was also investigated by means of TG and DTA under a streaming nitrogen gas atmosphere. Ammine complexes of nickel(II) decompose as shown in the following, the reaction orders and activation energies for steps a, b, c, and d being 0.5, 1.5, 1.0, and 0.5, and 16.5, 38.8, 25.3, and 79.4 kcal/mol, respectively.<BR>(<U>Remark: Graphics omitted.</U>)<BR>X-Ray diffraction data for [Ni(NH<SUB>3</SUB>)<SUB>6</SUB>]Cl<SUB>2</SUB>·0.5H<SUB>2</SUB>O, [Ni(NH<SUB>3</SUB>)<SUB>6</SUB>](NO<SUB>3</SUB>)<SUB>2</SUB>, [Ni(NH<SUB>3</SUB>)<SUB>5</SUB>]SO<SUB>4</SUB>·H<SUB>2</SUB>O, and [Ni(NH<SUB>3</SUB>)<SUB>2</SUB>]SO<SUB>4</SUB> powder are given.
