ABSTRACT: IN THE TITLE SYDNONE COMPOUND [SYSTEMATIC NAME: 3-(2,3-dimethyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-4-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(13)H(12)N(4)O(3), the oxadiazole and pyrazole rings are essentially planar [maximum deviations = 0.006?(1) and 0.019?(1)?Å, respectively] and are inclined at inter-planar angles of 37.84?(4) and 46.60?(4)°, respectively, with respect to the benzene ring. In the crystal, adjacent mol-ecules are inter-connected into a three-dimensional supra-molecular network via inter-molecular C-H?O hydrogen bonds. Weak inter-molecular ?-? aromatic stacking inter-actions [centroid-centroid distance = 3.5251?(5)?Å] further stabilize the crystal packing.

Project description:The title compound, C19H19N3O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the pyrazole ring adopts a slightly disordered half-chair conformation while in B it is planar [r.m.s. deviation = 0.0386?(15)?Å]. The dihedral angle between the mean planes of the two phenyl rings is 56.2?(8) in A and 38.2?(3)° in B. The N-phenyl substituent on the pyrazole ring is twisted by 46.5?(2) in A and 58.6?(4)° in B while the extended phenyl ring is twisted by 82.2?(8) in A and 87.5?(9)° in B. The mean plane of the amide group forms an angle of 74.8?(3) in A and 67.7?(1)° in B with respect to the phenyl ring. In addition, the amide group is rotated by 51.4?(1) in A and 53.6?(2)° in B from the the mean plane of the pyrazole ring. In the crystal, the two molecules are linked via N-H?O hydrogen bonds, supported by weak C-H?O inter-actions, forming dimers enclosing an R 2 (2)(10) ring motif. The dimers are linked via C-H?O inter-actions, forming a three-dimensional structure.

N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-4-yl)-2-(4-nitro-phen-yl)acetamide.

Project description:In the title compound, C19H18N4O4, the nitro-phenyl and phenyl rings are twisted by 67.0 (6) and 37.4 (4)°, respectively, with respect to the pyrazole ring plane [maximum deviation = 0.0042 (16) Å]. The dihedral angle between the mean planes of the phenyl rings is 59.3 (3)°. The amide group, with a C-N-C-C torsion angle of 177.54 (13)°, is twisted away from the plane of the pyrazole ring in an anti-periplanar conformation. In the crystal, N-H⋯O hydrogen bonds involving the carbonyl group on the pyrazole ring and the amide group, together with weak C-H⋯O inter-actions forming R 2 (2)(10) graph-set motifs, link the mol-ecules into chains along [100]. Additional weak C-H⋯O inter-actions involving the nitro-phenyl rings further link the mol-ecules along [001], also forming R 2 (2)(10) graph-set motifs, thereby generating (010) layers.

Crystal structure of ethyl N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-4-yl)carbamate.

Project description:In the title compound, C14H17N3O3, the dihedral angle between the benzene ring and the five-membered di-hydro-pyrazole ring is 52.26?(9)°. The ethyl ester group is approximately planar (r.m.s. deviation 0.0568?Å) and subtends an angle 67.73?(8)° to the pyrazole ring. In the crystal, molecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers with an R 2 (2)(10) ring motif.

Offset ?-? stacking inter-actions between the benzene rings [centroid-to-centroid distance = 3.8832?(12)?Å] further stabilize the crystal packing.

Co-crystallization of a neutral mol-ecule and its zwitterionic tautomer: structure and Hirshfeld surface analysis of 5-methyl-4-(5-methyl-1H-pyrazol-3-yl)-2-phenyl-2,3-di-hydro-1H-pyrazol-3-one 5-methyl-4-(5-methyl-1H-pyrazol-2-ium-3-yl)-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-1-ide monohydrate.

Project description:The title compound, 2C14H14N4O·H2O, comprises a neutral mol-ecule containing a central pyrazol-3-one ring flanked by an N-bound phenyl group and a C-bound 5-methyl-1H-pyrazol-3-yl group (at positions adjacent to the carbonyl substituent), its zwitterionic tautomer, whereby the N-bound proton of the central ring is now resident on the pendant ring, and a water mol-ecule of crystallization. Besides systematic variations in geometric parameters, the two independent organic mol-ecules have broadly similar conformations, as seen in the dihedral angle between the five-membered rings [9.72 (9)° for the neutral mol-ecule and 3.32 (9)° for the zwitterionic tautomer] and in the dihedral angles between the central and pendant five-membered rings [28.19 (8) and 20.96 (8)° (neutral mol-ecule); 11.33 (9) and 11.81 (9)°]. In the crystal, pyrazolyl-N-H⋯O(carbon-yl) and pyrazolium-N-H⋯N(pyrazol-yl) hydrogen bonds between the independent organic mol-ecules give rise to non-symmetric nine-membered {⋯HNNH⋯NC3O} and {⋯HNN⋯HNC3O} synthons, which differ in the positions of the N-bound H atoms. These aggregates are connected into a supra-molecular layer in the bc plane by water-O-H⋯N(pyrazolide), water-O-H⋯O(carbon-yl) and pyrazolyl-N-H⋯O(water) hydrogen bonding. The layers are linked into a three-dimensional architecture by methyl-C-H⋯π(phen-yl) inter-actions. The different inter-actions, in particular the weaker contacts, formed by the organic mol-ecules are clearly evident in the calculated Hirshfeld surfaces, and the calculated electrostatic potentials differentiate the tautomers.
