The crystal structures of four new chiral [1,2,3]triazolo[5,1-b][1,3,4]thia­diazines are described, namely, ethyl 5′-benzoyl-5′H,7′H-spiro­[cyclo­hexane-1,6′-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine]-3′-carboxyl­ate, C19H22N4O3S, ethyl 5′-(4-meth­oxy­benzo­yl)-5′H,7′H-spiro­[cyclo­hexane-1,6′-[1,2,3]triazolo[5,1-b][1,3,4]thia­dia­zine]-3′-carboxyl­ate, C20H24N4O4S, ethyl 6,6-dimethyl-5-(4-methyl­benzo­yl)-6,7-di­hydro-5H-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine-3-carboxyl­ate, C17H20N4O3S, and ethyl 5-benzoyl-6-(4-meth­oxy­phen­yl)-6,7-di­hydro-5H-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine-3-carboxyl­ate, C21H20N4O4S. The crystallographic data and cell activities of these four com­pounds and of the structures of three previously reported similar com­pounds, namely, ethyl 5′-(4-methyl­benzo­yl)-5′H,7′H-spiro­[cyclo­pentane-1,6′-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine]-3′-carboxyl­ate, C19H22N4O3S, ethyl 5′-(4-meth­oxy­benzo­yl)-5′H,7′H-spiro­[cyclo­pentane-1,6′-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine]-3′-carboxyl­ate, C19H22N4O4S, and ethyl 6-methyl-5-(4-methyl­benzo­yl)-6-phenyl-6,7-di­hydro-5H-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine-3-carboxyl­ate, C22H22N4O3S, are contrasted and com­pared. For both crystallization and an MTT assay, racemic mixtures of the corresponding [1,2,3]triazolo[5,1-b][1,3,4]thia­diazines were used. The main manner of mol­ecular packing in these com­pounds is the organization of either enanti­omeric pairs or dimers. In both cases, the formation of two three-centre hydrogen bonds can be detected resulting from intra­molecular N—H...O and inter­molecular N—H...O or N—H...N inter­actions. Mol­ecules of different enanti­omeric forms can also form chains through N—H...O hydrogen bonds or form layers between which only weak hydro­phobic contacts exist. Unlike other [1,2,3]triazolo[5,1-b][1,3,4]thia­diazines, ethyl 5′-benzoyl-5′H,7′H-spiro­[cyclo­hexane-1,6′-[1,2,3]triazolo[5,1-b][1,3,4]thia­diazine]-3′-carboxyl­ate contains mol­ecules of only the (R)-enanti­omer; moreover, the N—H group does not participate in any significant inter­molecular inter­actions. Mol­ecular mechanics methods (force field OPLS3e) and the DFT B3LYP/6-31G+(d,p) method show that the com­pound forming enanti­omeric pairs via weak N—H...N hydrogen bonds is subject to greater distortion of the geometry under the influence of the inter­molecular inter­actions in the crystal. For intra­molecular N—H...O and S...O inter­actions, an analysis of the noncovalent inter­actions (NCIs) was carried out. The cellular activities of the com­pounds were tested by evaluating their anti­proliferative effect against two normal human cell lines and two cancer cell lines in terms of half-maximum inhibitory con­centration (IC50). Some derivatives have been found to be very effective in inhibiting the growth of Hela cells at nanomolar and submicromolar con­centrations with minimal cytotoxicity in relation to normal cells.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
