Part of the crystal structure of 3-phenyl-1H-pyrazole-5-carboxylic acid showing the formation of a sheet of R22(8) and R66(28) rings lying parallel to (100): hydrogen bonds are shown as dashed lines. The original atomic coordinates (Zhang et al., 2007) have been used and, for the sake of clarity, the H atoms bonded to C atoms have all been omitted. |
