Figure 1
(a) The mol­ecular structure of seleno-L-cystine di­hydro­chloride. The right-hand part, coloured in a light tone, is generated by application of twofold rotation symmetry in space group C2; Se1*, C3* etc are generated by the symmetry code −x + 1, y, −z. Displacement ellipsoids are shown at the 50% probability level. (b) Best overlap between the structures of (I)[link] (dark grey O, N and C atoms) and (II) (light grey; Leela & Ramamurthi, 2007BB7) with a root-mean-square deviation of 0.133 Å. The view is along the twofold rotation axis (lens-shaped symbol), the dashed line gives the direction of the z axis.
