2-{(E)-[(2Z)-(3-Chloro-1-methyl-2,2-di-oxo-3,4-dihydro-1H-2,1-benzo-thia-zin-4-yl-idene)hydrazinyl-idene]meth-yl}phenol.

ABSTRACT: In the title compound, C(16)H(14)ClN(3)O(3)S, the thia-zine ring adopts a sofa (half-chair) conformation, with an r.m.s. deviation from the mean plane of 0.23?Å. The S atom and S-bonded C atom exhibit the maximum deviations from the thia-zine mean plane [-0.3976?(12) and 0.3179?(14)?Å, respectively]. The conformations around the double bonds in the R(2)C=N-N=CHR unit are Z and E. An intra-molecular O-H?N hydrogen bond with the hy-droxy group as donor generates an S(6) ring motif. In the crystal, pairs of weak C-H?O inter-actions connect the mol-ecules, forming inversion dimers.

N-[(2Z,4Z)-4-Benzyl-idene-6-chloro-1,4-dihydro-pyrido[2,3-d][1,3]thia-zin-2-yl-idene]benzamide.

Project description:In the crystal structure of the title compound, C(21)H(14)ClN(3)OS, mol-ecules assemble into inversion dimers via pairs of N-H⋯N hydrogen bonds involving the N-H hydrogen of the thia-zine ring and the N atom of the pyridine ring. There is a close intra-molecular contact [2.570 (2) Å] between the carbonyl O atom of the benzamide and the S atom of the puckered thia-zine ring. The title compound can exist in two tautomeric forms, viz. amino or imino. The observed structure is compatible with the imino form on the basis of observed residual electron density and the two C-N bond lengths of 1.308 (2) and 1.353 (2) Å.

2-{(E)-[(2Z)-2-(1,2-Di-hydro-phthalazin-1-yl-idene)hydrazinyl-idene]meth-yl}phenol.

Project description:The title compound, C15H12N4O, adopts an E conformation with respect to the azomethine bond and crystallizes in its hydrazinyl-idene tautomeric form. The dihedral angle between the ring systems is 15.98?(7)°. The phenol O-H group forms an intra-molecular O-H?N hydrogen bond. In the crystal, pairs of N-H?N and C-H?O hydrogen bonds link neighbouring mol-ecules into centrosymmetric dimers. These dimers are inter-connected by means of three types of ?-? stacking inter-actions. One, with a centroid-centroid distance of 3.577?(1)?Å [inter-planar separation = 3.4673?(6)?Å], connects adjacent mol-ecules into centrosymmetric dimers. The other two inter-actions, on the outward facing sides of the dimers, are between phenol rings of neighboring mol-ecules [centroid-centroid separation = 3.7907?(13)?Å and inter-planar separation = 3.5071?(8)?Å], and between phthalazin units [centroid-centroid separation = 3.6001?(12)?Å and inter-planar separation = 3.4891?(7)?Å]. In combination, the ?-? inter-actions lead to the formation of infinite layers with mol-ecules stacked along [0-11]. These layers are, in turn, connected with neighbouring layers through the N-H?N and C-H?O hydrogen bonds, yielding a three-dimensional supra-molecular architecture.

Project description:The asymmetric unit of the title compound, C21H19N3O3S, contains two independent mol-ecules. In one mol-ecule, the 1,3-thia-zolidine ring forms dihedral angles of 86.19?(8) and 8.37?(8)° with the phenyl and benzene rings, respectively.

There are weak C-H?O hydrogen bonds within these layers. Further weak C-H?O hydrogen bonding occurs between the layers to form a three-dimensional network. A weak C-H?? inter-action is also observed.
