Refinement of the crystal structure of the mineral claudetite, As2O3 (“Claudetite I”)


The mineral claudetite crystallizes monoclinic (a0=5.25,b0=12.99,c0=4.53 Å, β=93.880;Z=4) with space group P 21/n-C2h5. For 680 independent x-ray intensities, collected on aWeissenberg-type diffractometer, an R-factor of 4.9% was obtained. The AsO3-groups of the structure are connected by common oxygen corners in two dimensions forming puckered layers2As2O3.
