Diethyl [(3-cyano-1-phenyl­sulfonyl-1H-indol-2-yl)meth­yl]phospho­nate

In the title compound, C(20)H(21)N(2)O(5)PS, the indole ring is essentially planar, with a maximum deviation of −0.0083 (18) Å. The methyl C atom of the methyl­phospho­nate group and the S atom lie 0.104 (2) and −0.2158 (6) Å, respectively, from the indole mean plane. The sulfonyl-bound phenyl ring...

Sumario:In the title compound, C(20)H(21)N(2)O(5)PS, the indole ring is essentially planar, with a maximum deviation of −0.0083 (18) Å. The methyl C atom of the methyl­phospho­nate group and the S atom lie 0.104 (2) and −0.2158 (6) Å, respectively, from the indole mean plane. The sulfonyl-bound phenyl ring is almost perpendicular to the indole ring system, with a dihedral angle of 82.30 (8)°. The ethyl side chains are disordered over two sets of sites, with occupancy factors of 0.737 (5)/0.263 (5) and 0.529 (11)/0.471 (11). In the crystal, mol­ecules are linked into centrosymmetric dimers via C—H⋯O hydrogen bonds, resulting in an R (2) (2)(18) graph-set motif. The crystal structure is further stabilized by C—H⋯π inter­actions.
