The structure of the title compound, C 7 H 11 N 3 O 3 , 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-HÁ Á ÁN) and the other via an interaction from the hyd
In the title compound, C 15 H 14 ClF 3 N 2 O 2 , the benzene and pyrazolyl rings form a dihedral angle of 15.9 (3) .
In the title compound, C 21 H 21 ClN 2 O 2 , the pyrazole and chlorobenzene rings are coplanar and make a dihedral angle of 79.7 (2) with the tert-butylbenzene ring. The crystal structure displays intermolecular O-HÁ Á ÁO hydrogen bonding.
In the title compound, C~23~H~25~N~3~O~3~, all bond lengths and angles show normal values. The dihedral angles between the rings of the pyrazole and the unsubstituted and __tert__-butyl-substituted benzene rings are 8.6 (2) and 78.5 (3)°, respectively, while that between the two benzene rings is 76.
