5-Ethyl-4-methyl-1H-pyrazol-3(2H)-one.

ABSTRACT: In the title compound, C(6)H(10)N(2)O, the 2,3-dihydro-1H-pyrazole ring is approximately planar, with a maximum deviation of 0.013?(1)?Å. Pairs of inter-molecular N-H?O hydrogen bonds link neighboring mol-ecules into dimers, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by inter-molecular N-H?O hydrogen bonds. The crystal structure is further stabilized by C-H?? inter-actions.

In the title compound, C(6)H(10)N(2)O, the 2,3-dihydro-1H-pyrazole ring is approximately planar, with a maximum deviation of 0.013 (1) Å. Pairs of inter-molecular N-H⋯O hydrogen bonds link neighboring mol-ecules into dimers, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by inter-molecular N-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯π inter-actions. ...[more]

Project description:The asymmetric unit of the title compound, C(11)H(12)N(2)O, consists of two crystallographically independent mol-ecules (A and B) with similar geometries. Both mol-ecules exist in a keto form, the C=O bond length being 1.286?(2)?Å in A and 1.283?(2)?Å in B. The dihedral angles between the pyrazole ring and the attached phenyl ring are 43.28?(12) and 46.88?(11)°, respectively, for A and B. The ethyl unit in mol-ecule B is disordered over two positions with a site-occupancy ratio of 0.508?(5):0.492?(5). In the crystal, each of the independent mol-ecules forms a centrosymmetric dimer with an R(2) (2)(8) ring motif through a pair of N-H?O hydrogen bonds. These dimers are further connected into a three-dimensional network by inter-molecular N-H?O and C-H?O hydrogen bonds. Inter-molecular C-H?? inter-actions are also present.

4-Methyl-5-phenyl-1H-pyrazol-3(2H)-one.

Project description:The asymmetric unit of the title compound, C(10)H(10)N(2)O, contains two crystallographically independent mol-ecules with similar geometries, which exist in the keto form. The C=O bond lengths are 1.2878?(12)?Å in mol-ecule A and 1.2890?(12)?Å in mol-ecule B, indicating that the compound undergoes enol-to-keto tautomerism during the crystallization process. In mol-ecule A, the pyrazole ring is approximately planar [maximum deviation = 0.007?(1)?Å] and forms a dihedral angle of 36.67?(6)° with the attached phenyl ring. In mol-ecule B, the dihedral angle formed between the pyrazole ring [maximum deviation = 0.017?(1)?Å] and the phenyl ring is 41.19?(6)°. In the crystal, inter-molecular N-H?O hydrogen bonds link neighbouring mol-ecules into dimers generating R(2) (2)(8) ring motifs. These dimers are linked into ribbons along [101] via inter-molecular N-H?O hydrogen bonds, forming R(4) (2)(10) ring motifs.

Project description:The asymmetric unit of the title compound, C(27)H(24)N(4)O(2)·0.5C(2)H(6)O, comprises two crystallographically independent mol-ecules (A and B) with slightly different conformations, and one ethanol mol-ecule of crystallization. Intra-molecular C-H⋯O and O-H⋯O hydrogen bonds generate six- and eight-membered rings, producing S(6) and S(8) ring motifs, respectively. In mol-ecule A, one of the benzene rings is disordered over two positions, with site-occupancy factors of 0.542 (11) and 0.458 (11). The dihedral angles between the central benzene ring and the two outer benzene rings are 73.88 (9) and 82.6 (2)/88.9 (2)° in mol-ecule A, and 80.81 (8) and 79.38 (8)° in mol-ecule B. In the crystal structure, mol-ecules form infinite one-dimensional chains in the (101) plane. The crystal structure is stabilized by inter-molecular O-H⋯N, N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, weak C-H⋯π and π-π [centroid-centroid = 3.5496 (1) Å] inter-actions.
