4-[2-(1-Acetyl-2-oxopropyl-idene)-hydrazino]-N-(pyrimidin-2-yl) benzene-sulfonamide
(2009) Priyanka Rai; Shalini Upadhyay; M. Nethaji; K.K. Upadhyay
In the title compound, C15H15N5O 4S, the dihedral angle between the pyrimidine and benzene rings is 84.56 (2)°. Intra-molecular hydrazine-carbonyl N - H⋯O and inter-molecular sulfonamide-pyridimine N - H⋯N hydrogen bonds stabilize the mol-ecular and crystal structures, respectively.
Ethyl 3-oxo-2-[(4-sulfamoylphen-yl)hydra-zono]butyrate
(2009) K.K. Upadhyay; Priyanka Rai; Shalini Upadhyay; M. Nethaji
In the title compound, C12H15N3O5S, an intra-molecular N- H⋯O hydrogen bond between the hydrazine unit and one of the carbonyl groups may influence the mol-ecular conformation. In the crystal structure, inter-molecular N- H⋯O hydrogen bonds, including one which is bifurcated, link the mol-ecules into a two-dimensional network.
