3-Oxo-5-(piperidin-1-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile
In the title compound, C(9)H(12)N(4)O, the piperidine ring adopts a chair conformation and makes a dihedral angle of 42.49 (11)° with the approximately planar pyrazole moiety [maximum deviation = 0.038 (2) Å]. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds and a weak C-H⋯O inter-action link the mol-ecules into sheets lying parallel to (110).

The essentially planar pyrazole ring (r.m.s. deviation = 0.013 Å) in the title hemisolvate, C(31)H(33)N(7)S·0.5C(3)H(7)NO, is almost coplanar with the pendant thio-urea residue [N-N-C-S torsion angle = -173.2 (4)°] and slightly twisted with respect to the triazole ring [dihedral angle = 7.7 (3)°]. An intra-molecular thio-urea-pyrazole N-H⋯N hydrogen bond, via an S(5) loop, is formed. Supra-mole...

In the title compound, C(20)H(19)FN(6)S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angle between the least-squares plane through the pyrazole and triazole rings is 7.59 (9)°, and the triazole and attached benzene ring form a dihedral angle of 74.79 (9)°. The thio-urea group is coplanar with the pyrazole ring [N-N-C-S torsion angle ...
متن کامل4-[2-(4-Bromophenyl)hydrazinylidene]-3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-carbothioamide
In the title compound, C(11)H(10)BrN(5)OS, the approximately planar pyrazole ring [maximum deviation = 0.014 (2) Å] forms a dihedral angle of 5.49 (13)° with the benzene ring. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through inter-molecular N-H⋯S and N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (100). A sho...
