4-[(Ethoxy-imino)(phen-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

ABSTRACT: In the mol-ecule of the title compound, C(19)H(19)N(3)O(2), the central pyrazole ring makes dihedral angles of 9.89?(3) and 66.06?(5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05?(5)°. An intra-molecular C-H?O hydrogen bond forms a six-membered ring, producing an S(6) ring motif. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link each mol-ecule to two others, forming an infinite one-dimensional supra-molecular structure along the c axis.

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.

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.
