'''Reederite-(Y)''' is a rare mineral with the formula {{chem2|(Na,Mn,Fe)15(Y,REE)2(CO3)9(SO3F)Cl}}. It is the only known mineral with fluorosulfate ([[Chemistry:Fluorosulfonate|fluorosulfonate]]). "REE" in the formula stands for rare earth elements other than yttrium, that is mostly [[Chemistry:Cerium|cerium]], with traces of [[Chemistry:Neodymium|neodymium]], [[Chemistry:Dysprosium|dysprosium]], [[Chemistry:Lanthanum|lanthanum]] and [[Chemistry:Erbium|erbium]]. The formula also includes a Levinson suffix "-(Y)" pointing to the dominance of yttrium at the corresponding site. Reederite-(Y) crystallizes in the hexagonal crystal system with the space group ''P{{overline|6}}'', rarely seen among minerals.<ref>Grice, J.D., Gault, R.A., and Chao, G.Y., 1995.
