Figure 2
A partial packing plot showing the main supramolecular motif in I: a hydrogen-bonded dimer between inversion-related [symmetry code: (i) −x + 1, −y + 1, −z + 1] molecules. Strong O—H⋯O hydrogen bonds are shown as thick dashed lines, weaker C—H⋯O interactions as open dashed lines, and an unfavourable, forced close contact between hydrogen atoms as a dotted line. |
