Abstract- Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized  by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was repla...

The title compound, C(14)H(10)BrN(3)O(4), was synthesized by the reaction of 4-hydr-oxy-3-nitro-benzaldehyde with an equimolar quantity of 3-bromo-benzohydrazide in methanol. The mol-ecule displays an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 4.6 (2)°. The nitro group is almost coplanar with the attached benzene ring [dihedral angle = 4.7 (2)°]. In ...

The title compound, C(28)H(38)Br(2)N(2), is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central 1,4-diaza-butadiene mean plane [dihedral angle = 78.23 (3)°]. No hydrogen bonding or aromatic stacking is observed in the crystal structure.

In the title compound, C(15)H(13)BrN(2)O(3)·H(2)O, the dihedral angle between the two benzene rings is 13.92 (6)°. The meth-oxy group of the 4-hy-droxy-3-meth-oxy-phenyl is almost coplanar with its bound benzene ring, as seen by the C(meth-yl)-O-C-C torsion angle of -0.35 (16)°. In the crystal, mol-ecules are linked into a three-dimensional network by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and a...
