Figure 1
A molecular diagram of (I), showing the way in which chains are formed along the b axis. Independent atoms are drawn as octant-shaded displacement ellipsoids at the 40% probability level, connected by solid bonds, while symmetry-related atoms are shown as open ellipsoids connected by hollow bonds. H atoms have been omitted for clarity. [Symmetry codes: (i) x, −y + 1, z; (ii) −x + , −y + , −z; (iii) −x + , y + , −z.] |
