The arrangement of the ions of (I), viewed along the [001] axis. The weak C—H⋯O interactions between the sheets are represented by dashed lines. H atoms not involved in these interactions have been omitted for clarity. [Symmetry codes: (i) x, −y + , z; (vi) −x + , −y + 1, z + ; (vii) −x, y + , −z + 1.] |
