N2 - The crystal structure of natural zippeite,K1.85H+0.15[(UO2)4O2(SO4)2(OH)2](H2O)4, from Jáchymov, Czech Republic, has been determined by single-crystal X-ray diffraction. Zippeite is monoclinic, space group C2/m, with a 8.7802(6), b 13.9903(12), c 8.8630(6) A, beta 104.524(7), V 1053.92(12) A3. The structure consists of structural sheets of the zippeite uranyl anion topology and an interlayer, in which split K atoms and disordered O atoms (of the H2O groups) are located. The structure unit [(UO2)4O2(SO4)2(OH)2]2– is novel for both natural and synthetic compounds, but generally consistent with the known zippeite-type structures.
