Staurolite Koch-Muller M, Kahlenberg V, Bubenick W, Gottschalk M European Journal of Mineralogy 10 (1998) 453-460 Crystal-structure refinement of synthetic Fe- and Mg-staurolite by Rietveld analysis of X-ray powder-diffraction data Sample: Fe-staurolite synthesized at 5 kbar Note: These coordinates do not reproduce the reported bond lengths, but Koch-Muller tells me that the coordinates are correct, and the reported bond lengths were incorrect. _database_code_amcsd 0006728 CELL PARAMETERS: 7.8783 16.6172 5.6591 90.000 90.000 90.000 SPACE GROUP: Ccmm X-RAY WAVELENGTH: 1.541838 Cell Volume: 740.863 Density (g/cm3): 3.763 MAX.
