5-tert-Butyl-4-nitro-1H-pyrazol-3-ol

D. E. Lynch and I. McClenaghan

Abstract: The structure of the title compound, C₇H₁₁N₃O₃, consists of molecules that pack in a linear hydrogen-bonded ribbon motif. This hydrogen-bonding arrangement is constructed through two dimer formations, one that is atypical of pyrazoles (N-HN) and the other via an interaction from the hydroxy OH group to one of the nitro O atoms.
