In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazo...

In the title compound, C(14)H(18)N(2)O(3)S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005 (1) Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09 (5)°. Pairs of inter-molecular N-H⋯O and O⋯H⋯N hydrogen bonds form dimers between neighboring mol-ecules, generating R(2) (2)(10) ring motifs. These dimers are further linked by intermolecul...

In the title mol-ecule, C(14)H(15)N(3)O(4)S, the pyrazole ring is aligned at a dihedral angle of 55.5 (1)° with respect to the benzene ring; the mean planes of the acetyl substituents are twisted by 13.4 (3) and 30.1 (3)° with respect to the pyrazole ring. Inter-molecular classical N-H⋯O and weak C-H⋯O hydrogen bonding links the mol-ecules, forming a three-dimensional network architecture in th...
