(a) A view of a disordered propionic acid mol­ecule with displacement ellipsoids shown at the 30% probability level. (b) Section of the difference electron density map (Petříček et al., 2014BB11) through the atoms C22, C23 and C24bx. This section shows the region of the disordered propionic acid mol­ecule in part. Increments of positive and negative contours are 0.01 and 0.05 e Å−3. [Symmetry codes: (i) x − [{1\over 2}], −y + [{1\over 2}], −z + 1; (vii) −x + 1, −y, −z + 1; (viii) −x + [{3\over 2}], −y + [{1\over 2}], z − [{1\over 2}]; (ix) x, −y, z − [{1\over 2}]]. The disordered atoms are related by a symmetry operation (Wyckoff position c) (x) −x + 1, y, −z + 1/29. For colours, see caption for Fig. 1[link].
