Abstract
Single crystal X-ray structural data (T - 300 K) are reported for felsöbänyaite and basaluminite, AU (SO4) (OH)I0.4H2O. The X-ray work confirmed the identity of these two mineral species within limits of error. Structure parameters for felsöbänyaite: a = 13.026(1) Ä; b = 10.015(1) A; c = 11.115(1) Ä; ß = 104.34(1)°; Z = 4; space group P21-C2": 234 variable parameters were refined to R = 0.101, Rw = 0.092; 1044 X-ray reflections with Fo > l a Fo and sin x>/\ < 60°. The atomic arrangement exhibits a typical sheet structure, in which the individual AlOr, octahedra are combined via common O atom corners and edges to AI8O22 layers. These layers are interconnected by hydrogen bridges to SO4 tetrahedra and water molecules, forming the three dimensional arrangement. Basaluminite is a microcrystalline variety of felsöbänyaite.
