(2E)-1-(4-Bromo­phen­yl)-3-[3-(4-meth­oxy­phen­yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one

The pyrazole ring in the title compound, C25H19BrN2O2, is almost planar (r.m.s. deviation = 0.003 Å) and forms dihedral angles of 7.56 (13) and 56.48 (13)° with the N- and C-bound benzene rings, respectively. The prop-2-en-1-one residue has an E conformation about the C=C double bond [1.328 (4) Å] and is almost coplanar with the pyrazole ring [C-C-C-C torsion angle = -174.4 (3)°]. A twist betwe...

(2E)-1-(2,4-Dichloro­phen­yl)-3-[3-(4-nitro­phen­yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one

In the title compound, C(24)H(15)Cl(2)N(3)O(3), the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780 Å), but the mean planes of the two components are inclined at an angle of 9.95 (7)°. The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95 (7), 24.54 (6) and 43.02 (6)° with...

(2E)-3-(1,3-Diphenyl-1H-pyrazol-4-yl)-1-phenyl­prop-2-en-1-one

In the title compound, C(24)H(18)N(2)O, the pyrazole ring is essentially planar [maximum deviation = 0.004 (1) Å] and makes dihedral angles of 18.07 (4), 48.60 (4) and 9.13 (5)° with the phenyl rings. In the crystal, adjacent mol-ecules are connected via inter-molecular C-H⋯O hydrogen bonds, forming dimers. Furthermore, the crystal structure is stabilized by weak C-H⋯π and π-π inter-actions, wi...

1,5-Dimethyl-2-phenyl-1H-pyrazol-3(2H)-one–4,4′-(propane-2,2-di­yl)bis­[1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one] (1/1)

The asymmetric unit of the title compound, C11H12N2O·C25H28N4O2, contains two different mol-ecules. The smaller is known as anti-pyrine [systematic name: 1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one] and the larger is built up from two antypirine mol-ecules which are connected through a C atom of the pyrazolone ring to a central propanyl part [systematic name: 4,4'-(propane-2,2-di-yl)bis-[1,5-dim...

(3,5-Dimethyl-1H-pyrazol-1-yl){3-[(3,5-dimethyl-1H-pyrazol-1-yl)carbon­yl]-5-methyl­indolizin-1-yl}methanone

There are two independent mol-ecules in the asymmetric unit of the title compound, C21H21N5O2. In each mol-ecule, the indolizine ring system is essentially planar, with r.m.s. deviations of 0.030 and 0.028 Å. The dihedral angles between the indolizine ring system and the pyrazole rings are 54.7 (3) and 8.6 (3)° in one mol-ecule and 54.4 (3) and 6.6 (3)° in the other. In the crystal, weak C-H⋯O ...
