This report presents the first crystal structure determination of the mineral schaurteite, ideally Ca(3)Ge(SO(4))(2)(OH)(6)·3H(2)O, tricalcium germanium bis-(sulfate) hexa-hydroxide trihydrate. This single-crystal X-ray diffraction study investigated a natural sample from the type locality at Tsumeb, Namibia. Schaurteite is a member of the fleischerite group of minerals, which also includes fleischerite, despujolsite, and mallestigite. The structure of schaurteite consists of slabs of Ca(O,OH,H( ...[more]
