Abstract
The title compound C32H27NO5S belongs to the monoclinic system, space group P21/c with a = 14.4530(5) Å, b = 13.9185(5) Å, c = 13.5714(4) Å, α = γ = 90°, β = 87.174(3)°, V = 2726.76(16) Å3, Z = 4, Dc = 1.310 g/cm3, F(000) = 1128, R = 0.053 and wR = 0.133, S = 1.03, T = 296 K. In the title compound, the naphthalene unit is planar (r.m.s. deviation = 0.0227 Å). The dihedral angle between the naphthalene unit and nitro-benzenesulfonic acid, 2-phenyl-ethyl and 4-phenyl-ethyl are 49.68(05)°, 82.96(06)°, and 81.94(07)° respectively. The structure is stabilized by intra- and intermolecular C-H…O hydrogen bonds.
