    www.ncbi.nlm.nih.gov/pmc/articles/PMC3254272 Pyrosmalite-(Fe) is isotypic with pyrosmalite-(Mn) and its structure is characterized by a stacking of brucite-type layers of FeO 6-octa­hedra alternating with sheets of SiO 4 tetra­hedra along [001]. These sheets consist of 12-, six- and four-membered rings of tetra­hedra in a 1:2:3 ratio.
