Abstract
Hohmannite is a hydrated sulphate of ferric iron with the formula Fe2(SO4)2(OH)2.7H2O (Palache, Berman, and Frondel, 1951).Figs. 1 and 2 illustrate the structure of hohmannite. The first shows a complex chain of Fe(O, H2O)6 octahedra and SO4 tetrahedra, which runs along the c axis; the second visualizes the water molecules and an hypothetical hydrogen-bonds system obtained on the basis of electrostatic and geometrical considerations.Keywords
