The phenyl rings are oriented at a dihedral angle...

The title compound, C29H24N2OS, contains a pheno-thia-zine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C-C single bond. The pheno-thia-zine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings. The dihedral angle between the mean planes of the carbazole and pheno-thia-zine units is 27.28 (5)°. In t...

In the title compound, C(11)H(9)NO(3)S(2)·CH(4)O, the dihedral angle between the aromatic rings is 3.57 (16)° and intra-molecular O-H⋯O and C-H⋯S inter-actions occur. In the crystal, the thia-zolidin-4-one mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains. The hydrogen-bond motifs lead to S(5), S(6) and R(3) (3)(8) ring motifs. There exist C=O⋯π inter-actions between the heterocycli...

In the title compound, C(9)H(7)N(3)O(3)S, the nitro and thia-zolidinone moieties are inclined with respect to the aromatic ring at dihedral angles of 9.57 (16) and 78.42 (4)°, respectively. In the crystal, N-H⋯O hydrogen bonding connects the mol-ecules along the c and a axes to form a two-dimensional polymeric network. A weak S⋯O inter-action [3.2443 (11) Å] and phenyl ring to phenyl ring off-s...
