4-[(4-Chloro-phen-yl)(5-hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

ABSTRACT: 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?? 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.

1-(5-Hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone: a new monoclinic polymorph.

Project description:The title compound, C(12)H(12)N(2)O(2), crystallized in the monolinic space group P2(1)/n, with two independent mol-ecules (A and B) in the asymmetric unit. This is in contrast to the first monoclinic polymorph reported [Cingolani et al. (2002 ?). Inorg. Chem.41, 1151-116], which crystallized in the space group C2/c with one independent mol-ecule per asymmetric unit. The dihedral angles between the two rings differ slightly; in mol-ecule A it is 4.90?(11)° and in mol-ecule B it is 16.05?(13)°. In both mol-ecules, there is an intra-molecular O-H?O hydrogen bond involving the hydroxyl substituent and the carbonyl O atom of the adjacent acetyl group. In the crystal structure, mol-ecules A and B are linked via a C-H?N inter-action. There are also some weak C-H?? inter-actions involving the phenyl ring of mol-ecule A and H atoms of the acetyl groups of both mol-ecules.

Crystal structure of (4E)-4-(8-meth-oxy-2H-chromen-2-yl-idene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

Project description:In the title compound, C20H16N2O3, the phenyl substituent attached to the pyrazole ring makes a dihedral angle of 4.87?(7)° with the rest of the mol-ecule.

Similarly, ?-? inter-actions are present at a centroid-centroid distance of 3.601?(1)?Å between the oxygen-containing heterocyclic ring and meth-oxy substituted aromatic ring of a neighbouring mol-ecule. Additional C-H?? and C=O?? inter-actions are also observed.

Project description:In the title compound, C(26)H(23)N(5)O(2)S, an intra-molecular N-H?O inter-action generates an S(6) ring. The essentially planar S(6) and pyrazole rings [maximum deviations = -0.0270?(14) and 0.0195?(15)?Å, respectively] are nearly coplanar, making a dihedral angle of 3.94?(6)°.
