Figure 1
The centrosymmetric hydrogen-bonded dimer of (I). All non-H atoms of the asymmetric unit and selected non-H atoms of the symmetry related molecule [symmetry code: (i) −x + 2, −y − 1, −z] are labelled. Non-H atoms are shown as 50% probability ellipsoids and H atoms are shown as open circles. Dashed lines represent H⋯O contacts. |
