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.
