Point group symmetry of epsomite crystal

Epsomite is a hydrated magnesium sulphate and its equilibrium shape is illustrated. It is particularly difficult to visualise the diads passing through the vertical edges of the crystal without having access to an actual crystal. This movie demonstrates the 222 point group symmetry of the crystal shape consistent with the orthorhombic crystal class. • http://www.msm.cam.ac.uk/phase-trans/... • Created by H. K. D. H.
