(hexahydrate). It is also hydrated equivalent of cobaltkieserite. It occurs together with moorhouseite within efflorescences found in the Magnet Cove Barium Corporation mine in Walton, Nova Scotia, Canada.

Notes on chemistry

Relatively high amounts of nickel and manganese were reported, with trace amounts of copper and iron.

Crystal structure

Analysis of synthetic analogue of moorhouseite revealed, that its structure may be described as containing:Elerman, Y., 1988. Refinement of the crystal structure of CoSO₄^.6H₂O. Acta Crystallographica C44, 599-601 * Co(H₂O)₆ octahedra, forming alternate layers * SO₄ tetrahedra * hydrogen bonds (two per a single water molecule)
