Figure 5
Part of the crystal structure of (I), showing the formation of the centrosymmetric R22(22) motif which links the (01) sheets into a bilayer. For the sake of clarity, the unit-cell outline and H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) are at the symmetry position (−x + 1, −y, −z + 1). |
