(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) ![]() ![]() |
