Abstract
The title compound, C19H16ClNO3S, consists of chloro-phenyl methyl-idene and di-hydro-benzo-thia-zine units linked to an acetate moiety, where the thia-zine ring adopts a screw-boat conformation. In the crystal, two sets of weak C-HPh⋯ODbt (Ph = phenyl and Dbt = di-hydro-benzo-thia-zine) hydrogen bonds form layers of mol-ecules parallel to the bc plane. The layers stack along the a-axis direction with inter-calation of the ester chains. The crystal studied was a two component twin with a refined BASF of 0.34961 (5). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (37.5%), H⋯C/C⋯H (24.6%) and H⋯O/O⋯H (16.7%) inter-actions. Hydrogen-bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Computational chemistry indicates that in the crystal, C-HPh⋯ODbt hydrogen bond energies are 38.3 and 30.3 kJ mol-1. Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. Moreover, the anti-bacterial activity of the title compound has been evaluated against gram-positive and gram-negative bacteria.

Abstract
The title compound, C18H12Cl2N2OS, consists of a di-hydro-benzo-thia-zine unit linked by a -CH group to a 2,4-di-chloro-phenyl substituent, and to a propane-nitrile unit is folded along the S⋯N axis and adopts a flattened-boat conformation. The propane-nitrile moiety is nearly perpendicular to the mean plane of the di-hydro-benzo-thia-zine unit. In the crystal, C-HBnz⋯NPrpnit and C-HPrpnit⋯OThz (Bnz = benzene, Prpnit = propane-nitrile and Thz = thia-zine) hydrogen bonds link the mol-ecules into inversion dimers, enclosing R 2 2(16) and R 2 2(12) ring motifs, which are linked into stepped ribbons extending along [110]. The ribbons are linked in pairs by complementary C=O⋯Cl inter-actions. π-π contacts between the benzene and phenyl rings, [centroid-centroid distance = 3.974 (1) Å] may further stabilize the structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (23.4%), H⋯Cl/Cl⋯H (19.5%), H⋯C/C⋯H (13.5%), H⋯N/N⋯H (13.3%), C⋯C (10.4%) and H⋯O/O⋯H (5.1%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Computational chemistry calculations indicate that the two independent C-HBnz⋯NPrpnit and C-HPrpnit⋯OThz hydrogen bonds in the crystal impart about the same energy (ca 43 kJ mol-1). Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Abstract
The title compound, C20H16Cl2N2O3S, is built up from a di-hydro-benzo-thia-zine moiety linked by -CH- and -C2H4- units to 2,4-di-chloro-phenyl and 2-oxo-1,3-oxazolidine substituents, where the oxazole ring and the heterocyclic portion of the di-hydro-benzo-thia-zine unit adopt envelope and flattened-boat conformations, respectively. The 2-carbon link to the oxazole ring is nearly perpendicular to the mean plane of the di-hydro-benzo-thia-zine unit. In the crystal, the mol-ecules form stacks extending along the normal to (104) with the aromatic rings from neighbouring stacks inter-calating to form an overall layer structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (28.4%), H⋯Cl/Cl⋯H (19.3%), H⋯O/O⋯H (17.0%), H⋯C/C⋯H (14.5%) and C⋯C (8.2%) inter-actions. Weak hydrogen-bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Abstract
The title compound, C18H12FNOS, is built up from a 4-fluoro-benzyl-idene moiety and a di-hydro-benzo-thia-zine unit with a propynyl substituent, with the heterocyclic portion of the di-hydro-benzo-thia-zine unit adopting a shallow boat conformation with the propynyl substituent nearly perpendicular to it. The two benzene rings are oriented at a dihedral angle of 43.02 (6)°. In the crystal, C-HFlurphen⋯FFlurphen (Flurphen = fluoro-phen-yl) hydrogen bonds link the mol-ecules into inversion dimers, enclosing R 2 2(8) ring motifs, with the dimers forming oblique stacks along the a-axis direction. Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (33.9%), H⋯C/C⋯H (26.7%), H⋯F/F⋯H (10.9%) and C⋯C (10.6%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.
