Dimethyl [(4-fluoro-phen-yl)(6-methoxy-benzothia-zol-2-ylamino)meth-yl]phospho-nate
Abstract:
In the mol-ecule of title compound, C(17)H(18)FN(2)O(4)PS, both the benzene ring with its conjunction C atom and the benzothia-zole ring with its conjunction N atom are close to planar (the maximum deviations are 0.0267 and 0.0427 Å for the benzene and benzothiazole rings, respectively), the dihedral angle between the planes of the benzothia-zole and benzene rings is 119.05 (3)°. The mol-ecular packing is stabilized by inter-molecular N-H⋯O, C-H⋯N and C-H⋯F hydrogen bonding, and by C-H⋯π and π-π stacking inter-actions [centroid-centroid distances = 2.99 (2), 2.96 (3), 2.88 (2) and 3.773 (4) Å].
