Polymorph (I): projection of the chains parallel to the c axis. In this projection all O atoms are hidden behind their respective C atoms. The twofold axes within the molecules are at x = 0, y = 0 and x = ¼, y = ¼, and all equivalent positions to these. The parent molecule, corresponding to the deposited coordinates, is at the centre of the cell (x = ½, y = ½). |
