Figure 4
A view of azetidine along the c axis, showing one chain linked by co-operative N—H⋯N hydrogen bonds (dashed lines) propagating along a 21 screw axis parallel to the b axis. The two crystallographically distinct mol­ecules and their symmetry equivalents are distinguished by their shading. H atoms bound to C atoms have been omitted. [Symmetry codes: (i) −x + 1, y − [{1\over 2}], −z + [{1\over 2}]; (ii) −x + 1, y + [{1\over 2}], −z + [{1\over 2}].]
