ALUMINOPYRACMONITE* Z = 6. In the crystal structure of aluminopyracmonite [refined F. Demartin, C. Castellano, and I. Campostrini (2013) Alumi- to R1 = 0.0258 for 998 unique I > 2σ(I) reflections] two types of Al octahedra are linked by corner sharing with (SO4) tetrahedra nopyracmonite, (NH4)3Al(SO4)3, a new ammonium alumin- ium sulfate from La Fossa crater, Vulcano, Aeolian Islands, with two possible conformation with 2/3 and 1/3 occupation, to Italy. Mineralogical Magazine, 77(4), 443–451. form the infinite [Al(SO4)3]∞ chains made by the AlO6 octahedra which share all their corners with sulfate tetrahedra. The voids Aluminopyracmonite (IMA 2012-075), ideally located between these parallel chains extending along [001] host the ammonium ions that are hydrogen-bonded with the (NH4)3Al(SO4)3, is a new mineral from La Fossa crater, Vul- cano, Aeolian Islands, Sicily, Italy.
