A comparison of the crystal packing in compounds (I) and (II). (a) The crystal packing in compound (II), with the N and C atoms of the caprolactam rings omitted for clarity. (b) A schematic view of the NaCl packing motif in (II). (c) A schematic view of the NaCl packing motif in (I). Dark and light balls denote the centres of the cations and anions, respectively, and thin lines show cell edges. |
