Figure 2
A cell view of (I), approximately down the c axis (MERCURY; Macrae et al., 2006), showing the `sandwich' crystal packing along the a axis: dotted lines represent hydrogen-bonding interactions. For clarity, only one set of H and I atoms involved in hydrogen bonding is labelled. [Symmetry codes: (i) x, −y + , z (ii) −x, y + , −z + 1; (iii) x, y + 1, −1 + z.] |
