The synthesis and crystal structures of 2-(4-fluoro-phen-yl)-3-phenyl-2,3-di-hydro-4 H -pyrido[3,2- e ][1,3]thia-zin-4-one toluene hemisolvate ( 1 ), C 19 H 13 FN 2 OS·0.5C 7 H 8 , and 2-(4-nitro-phen-yl)-3-phenyl-2,3-di-hydro-4 H -pyrido[3,2- e ][1,3]thia-zin-4-one iso-propanol 0.25-solvate 0.0625-hydrate ( 2 ), C 19 H 13 N 3 O 3 S·0.25C 3 H 7 O·0.0625H 2 O, are reported. Both are racemic mixtures (centrosymmetric crystal structures) of the individual com-pounds and incorporate solvent mol-ecules in their structures. Compound 2 has four thia-zine mol-ecules in the asymmetric unit. All the thia-zine rings in this study show an envelope pucker, with the C atom bearing the substituted phenyl ring displaced from the other atoms. The phenyl and aryl rings in each of the mol-ecules are roughly orthogonal to each other, with dihedral angles of about 75°. The extended structures of 1 and 2 are consolidated by C-H⋯O and C-H⋯N(π), as well as T-type (C-H⋯π) inter-actions. Parallel aromatic ring inter-actions (π-π stacking) are observed only in 2 .
