Pb2(Fe3+Te6+)[AlSi3O8]O6
Was originally assumed to be mica-like, Pb2(Fe3+,Mn3+)Te4+(AlSi3O10)O2(OH)2.H2O. Structure determination shows that Te is 6+, formula is anhydrous, and the aluminosilicate layer is actually a kampfite/cymrite-like double sheet; the sheets alternate with phyllotellurate [(FeTe)O6]3- layers; there is a Pb2[FeTeO6] module of a topology similar to a slab in rosiaite.
