Figure 4
Octahedron formed by the arrangement of molecules linked by the N—H⋯N hydrogen bond and the weak N—H⋯N contact in the low-temperature phase of cyclopropylamine (de Boer et al., 1986). Only the non-H atoms are shown. The bond distances (edges) of the polyhedron are displayed. The long (3.629 Å) N⋯N contact is omitted. |
