The crystal structure of the monoclinic form ofAs2O3(claudetite II)

Abstract

Claudetite II crystallizes monoclinic (a0=7.99,b0=4.65,c0=9.12 Å, β=78.3°;Z=4) with space group P21/n-C2h5. AnR-factor of 0.07 was obtained from 568 observed independent reflections using individual anisotropic temperature factors. Each of the two crystallographically different As-atoms forms a flat trigonal pyramid with three oxygens. The pyramids are connected in two dimensions by common corners to form undulating sheets parallel to (001).
