The crystal structure of kastningite, a new mineral from Waidhaus, Bavaria, Germany, has been determined. Ideal formula from X-ray structure analysis is Mn(H2O)4[Al2(OH)2(H2O)2(PO4)2] · 2 H2O. Lattice parameters are a = 10.205(1), b...
Large Mn(PO3OH)3H(2)O crystals have been prepared from aqueous solutions containing MnCl2 and (NH4)(2)HPO4 by an evaporation-induced crystal growth technique. The slow solvent evaporation at room temperature maintained the supersatura...
The rockbridgeite group has been officially established by the IMA Commission on New Minerals, Nomenclature and Classification. The general formula is b...
