Figure 3
A view of the crystal packing of (I) in the (100) plane, showing how the hydrogen bonds (dashed lines) involving perchlorate counter-ions form a two-dimensional layer. All H atoms not involved in the depicted interactions and hydrogen bonds within the dimer and the two-dimensional layer have been omitted for clarity. [Symmetry codes: (i) −x + 1, −y + 2, −z + 1; (ii) −x + 1, −y + 1, −z + 1; (v) −x, −y + 1, −z + 1; (vi) x − 1, y, z.] |
