Ethyl 1-(4-methylphenyl)-5-phenyl-4-phenylsulfonyl-1H-pyrazole-3-carboxylate
The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007 Å) and the N- and C-bound phenyl rings are 48.10 (7) and 72.01 (7) °, respectively, indicating that the planes through the residues...

Sumario: | The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007 Å) and the N- and C-bound phenyl rings are 48.10 (7) and 72.01 (7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO(2) group is also twisted out of this plane, with an O—C—C—N torsion angle of −29.04 (11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonylphenyl ring to the other. The dihedral angle between the two ring planes is 70.63 (7) °. Supramolecular arrays are formed in the crystal structure sustained by C—H⋯O and C—H⋯π(pyrazole) interactions and methyl-C—H⋯π(N-bound benzene) contacts. |
