Moorhouseite is a rare mineral with the formula CoSO4•6H2O, a naturally occurring cobalt(II) sulfate hexahydrate. It is the lower-hydrate-equivalent of bieberite (heptahydrate) and aplowite (hexahydrate). It is also hydrated equivalent of . It occurs together with moorhouseite within efflorescences found in the Magnet Cove Barium Corporation mine in Walton, Nova Scotia, Canada.[6][7]
Notes on chemistry[]
Relatively high amounts of nickel and manganese were reported, with trace amounts of copper and iron.[8]
Crystal structure[]
Analysis of synthetic analogue of moorhouseite revealed, that its structure may be described as containing:[9]
- Co(H2O)6 octahedra, forming alternate layers
- SO4 tetrahedra
- hydrogen bonds (two per a single water molecule)
