3-(2,5-Dimethyl-furan-3-yl)-1H-pyrazol-5-ol-ethyl 3-(propan-2-yl-idene)carbazate (1/1).

ABSTRACT: In the title 1:1 adduct, C(6)H(12)N(2)O(2)·C(9)H(10)N(2)O(2), the maximum deviations from the 1H-pyrazole-5-ol and furan rings are 0.014?(1) and 0.003?(1)?Å, respectively. The dihedral angle formed between the 1H-pyrazol-5-ol and 2,5-dimethyl-furan rings is 21.07?(5)°. In the crystal, pairs of inter-molecular O-H?N hydrogen bonds form inversion dimers of the 3-(2,5-dimethyl-furan-3-yl)-1H-pyrazol-5-ol species, generating R(2) (2)(8) ring motifs. Mol-ecules are further linked by inter-molecular N-H?O, N-H?N and C-H?O hydrogen bonds to form ribbons along the [010] direction containing bifurcated R(1) (2)(5) and R(2) (1)(7) ring motifs. Further stablization of the packing is provided by weak ?-? [centroid-centroid distance = 3.5686?(15)?Å] and C-H?? inter-actions.
