Abstract

The asymmetric unit of the title compound, C(21)H(22)N(4)O(4)S, contains two mol-ecules (A and B), in which the thia-zine rings adopt an S-envelope conformation with the S atoms displaced by 0.621 (2) and 0.697 (2) Å from the mean planes formed by the remaining ring atoms. The dihedral angles between the N-methyl-acetamide groups and the meth-oxy-benzene rings are 8.67 (10) and 54.49 (6)° in the two mol-ecules and the equivalent torsion angles in the N-methyl-acetamide chains connecting the ring systems also differ. In the crystal, N-H⋯O hydrogen bonds connect the components into C(4) [100] chains of alternating A and B mol-ecules. The packing is consolidated by weak C-H⋯O inter-actions, which generate a three-dimensional network.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
