ABSTRACT: The imino-carbon double-bond in the title Schiff base, C(20)H(21)N(3)O(3), has an E configuration; the six-membered aromatic substituent (r.m.s. deviation = 0.012?Å) is nearly coplanar with five-membered pyrazole substituent (r.m.s. deviation = 0.031?Å), the dihedral angle between the two systems being 11.4?(1)°]. The phenyl ring connected to the pyrazole ring is aligned at 45.5?(1)° with respect to this five-membered ring. The N atoms in the ring show pyramidal coordinations.

Project description:The title compound, C(21)H(23)N(3)O(4), adopts an E configuration about the central C=N double bond and the pyrazolone ring is almost planar, with a maximum deviation of 0.042 (1) Å. The central pyrazolone ring makes dihedral angles of 51.96 (5) and 3.82 (5)° with the attached phenyl and the trimeth-oxy-substituted benzene rings, respectively. The dihedral angle between the phenyl ring and the trimeth-oxy-substituted benzene ring is 50.19 (5)° and an intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.

In the crystal, mol-ecules form centrosymmetric dimers via donor-acceptor π-π inter-actions, with a centroid-centroid distance of 3.401 (1) Å.

Crystal structure of 4-[(E)-(4-hy-droxy-benzyl-idene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:The asymmetric unit of the title compound, C18H17N3O2, comprises three independent mol-ecules (1, 2 and 3). In mol-ecule 1, the dihedral angles between the pyrazolone ring and the pendant phenyl and hydroxybenzene rings are 54.43 (6) and 28.72 (6)°, respectively. The corresponding data for mol-ecule 2 are 86.84 (6) and 25.69 (5)°, respectively, and for mol-ecule 3 are 47.41 (7) and 17.09 (7)°, respectively. The three mol-ecules feature an intra-molecular C-H⋯O inter-action, which closes an S(6) ring in each case. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, which generate [100] chains incorporating all three asymmetric mol-ecules. Two weak C-H⋯O interactions connect three independent molecules to each other along the c-axis direction.
