Abstract

Abstract The X-ray powder pattern data of JCPDS card 6-226 of anhydrite have been reindexed. In the setting of space group Bmmb, a = 0.6992, b = 0.6998 and c = 0.6238 nm. The average of these data and of single crystal unit cell dimensions and atomic coordinates from the literature lead to the following bond lengths: S-O = 0.1473 nm (4x), Ca-O = 0.2343, 0.2461, 0.2508 (2x) and 0.2560 nm (2x).
