Nickelamide, Ni(NH₂)₂

Nickelamide, Ni(NH₂)₂, is precipitated as a red, flocculent mass when a solution of nickel thiocyanate in liquid ammonia is treated with an equivalent amount of potassamide solution. It reacts with water, producing nickel hydroxide and ammonia:

Ni(NH₂)₂ + 2H₂O = Ni(OH)₂ + 2NH₃

At 120° C. it yields nickel nitride.
