Nickel double salts

Nickel is one of the metals that can form Tutton's salts. The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium , or thallium. As a mineral the ammonium nickel salt, (NH4)2Ni(SO4)2 • 6H2O, can be called nickelboussingaultite. With sodium, the double sulfate is nickelblödite Na2Ni(SO4)2 • 4H2O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form. Double hydrides of nickel exist, such as Mg2NiH4. Lithium nickel hexachloride Li4NiCl6·10H2O is stable from 0 to 23°.
