Linnaeite is a cobalt sulfide mineral with the composition Co +2 Co +32 S 4. It was discovered in 1845 in Västmanland, Sweden, and was named to honor Carl Linnaeus (1707–1778). [2] Linnaeite forms a series with polydymite, Ni +2 Ni +32 S 4. [5] .

Some Ni-bearing or -rich "linnaeites" reported in the literature are probably grimmite. As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams. Please only use the official IMA–CNMNC symbol. Older variants are listed for historical use only. Warr, L.N. (2021).

The other known members of the series are siegenite, (Co,Ni) 3 S 4 with Co:Ni = 1:1; carrollite, Co 2 CuS 4; violarite, Ni 2 FeS 4; and polydymite, Ni 3 S 4. The linnaeites are usually associated ...
