Figure 3
A partial packing diagram of the type II ladder for (I). N+—H⋯O− hydrogen bonds are shown as dashed lines. The 2-propylammonium cation is disordered and only the major occupied site is shown. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry code: (i) x + , −y + , −z + 1.] |
