Nickel Molybdate, NiMoO₄

Nickel Molybdate, NiMoO₄, is prepared by fusing a mixture of sodium molybdate and chloride with nickel chloride. It occurs as green prisms. The hydrated ammoniate, NiMoO₄.NH₃.2H₂O, is obtained as greenish blue prisms by dissolving nickel hydroxide in ammoniacal ammonium molybdate.

Complex nickelo-molybdates have been prepared.
