2-{[2-(1-Methyl-2,2-dioxo-3,4-dihydro-1H-2?(6),1-benzothia-zin-4-yl-idene)hydrazin-1-yl-idene]meth-yl}phenol.

ABSTRACT: In the title compound, C(16)H(15)N(3)O(3)S, the dihedral angle between the aromatic rings is 8.18?(11)° and the C=N-N=C torsion angle is 178.59?(14)°. The conformation of the thia-zine ring is an envelope, with the S atom displaced by 0.8157?(18)?Å from the mean plane of the other five atoms (r.m.s. deviation = 0.045?Å). An intra-molecular O-H?N hydrogen bond closes an S(6) ring. In the crystal, weak C-H?O inter-actions link the mol-ecules, with all three O atoms acting as acceptors.

The mean planes of these rings are oriented at dihedral angles of 64.43 (13) and 28.6 (2)° in the two independent mol-ecules while the aromatic and thia-zine rings are twisted by dihedral angles of 8.73 (8) and 13.07 (2)°, respectively. In the crystal, C-H⋯O and C-H⋯Br inter-actions connect mol-ecules into chains propagating along the a axis.

Project description:In the title compound, C(10)H(11)N(3)O(2)S, the thia-zine ring exists in a conformation inter-mediate between twist-boat and half-chair.

Project description:In the title compound, C(10)H(10)N(2)O(2)S, the thia-zine ring approximates to an envelope form with the S atom in the flap position. The amide group attached to the acetate group is almost perpendicular to the mean plane of the thia-zine ring [dihedral angle = 88.83 (8)°]. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. Further N-H⋯O and C-H⋯O hydrogen bonds link the dimers into a three-dimensional network.

Project description:In the title mol-ecule, C(18)H(17)N(5)O(3)S(2), the heterocyclic thia-zine ring adopts a twist boat conformation, with the S and N atoms displaced by 0.480?(7) and 0.205?(8)?Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The pyrazole and benzene rings are tilted at an angle of 10.9?(2)° with respect to one another. The crystal structure is stabilized by inter-molecular N-H?O and C-H?N hydrogen bonds, resulting in dimers forming nine-membered rings of graph-set motif R(2) (2)(9). In addition, inter-molecular C-H?O inter-actions result in chains of mol-ecules along the c axis, further consolidating the crystal packing.
