5-Methyl-4-(5-methyl-3-oxo-2-phenyl-2,3-di-hydro-1H-pyrazol-4-yl)-2-phenyl-1H-pyrazol-3(2H)-one.

ABSTRACT: The title compound, C₂₀H₁₈N₄O₂, known as bis-pyrazolone, was crystallized from dimethyl sulfoxide. The structure has ortho-rhom-bic (Pbca) symmetry at 150 K, and displays both intra- and inter-molecular hydrogen bonding through C-H⋯O and N-H⋯O contacts, respectively. None of the phenyl and pyrazolone rings in the mol-ecule are coplanar. The dihedral angle between the pyrazolone rings is 66.18 (5)°.

4-[(5-Hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)phenyl-meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol hemisolvate.

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.

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:In the the title compound, C(27)H(23)ClN(4)O(2), the chloro-phenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O-H⋯O hydrogen bond generates an S(8) ring motif. The mol-ecules are linked into chains running along the c axis by N-H⋯N hydrogen bonds, and the chains are cross-linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions involving the chloro-phenyl ring.

Project description:In the title compound, C(21)H(17)N(3)O(4)·H(2)O, the coumarin ring system is almost planar (r.m.s. deviation = 0.002 Å) and makes dihedral angles of 1.50 (7) and 57.75 (7)° with the pyrazole and phenyl rings, respectively. The dihedral angle between the pyrazole and phenyl rings is 56.60 (9)°. The pyrazole ring adopts a twisted comformation. The mol-ecular conformation is stabilized by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds, both of which form S(6) ring motifs. In the crystal, each water mol-ecule is linked to its adjacent organic mol-ecule via pairs of O-H⋯O hydrogen bonds. The packing is further consolidated by pairs of inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into dimers; the dimers are stacked along the b axis.
