Wiklundite is a rare[2] and complex arsenite-silicate mineral with the formula Pb2(Mn2+,Zn)3(Fe3+,Mn2+)2(Mn2+,Mg)19(As3+O3)2(Si,As5+O4)6(OH)18Cl6. The mineral characterizes in a large c unit cell parameter.[1] It was found in Långban, Sweden - a home for many rare and exotic minerals.[3]
Relation to other minerals
Structure of wiklundite is unique.[1] A slightly chemically similar mineral, although lacking manganese and iron, is hereroite.[4]
