N′-(3-Ethoxy-2-hydroxybenzylidene)benzenesulfonohydrazide
There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(4)S, both of which are stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds lead to [101] chains of mol-ecules in the crystal structure.
متن کاملSynthesis and X-ray Crystal Structure of N’-Cyano-N,N’-dimethyl-4-nitrobenzohydrazide
Using a two-step procedure, N’-cyano-N,N’-dimethyl-4-nitrobenzohydrazide was synthesized. The structure was established using single crystal X-ray diffraction. It crystalized in the orthorhombic space group P212121 where a = 8.1974(6), b = 10.6696(7), and c = 12.9766(8) Å. The first reported crystal structure of an acyclic cyanohydrazide is discussed with a focus on the geometry of the hydrazid...

متن کاملN-(4-Chlorobenzoyl)-N′-(3-fluorophenyl)thiourea
In the title compound, C(14)H(10)ClFN(2)OS, the mol-ecule adopts a trans-cis geometry of the thio-urea unit. The dihedral angles between the benzene rings is 34.47 (7)°. The crystal packing features inter-molecular N-H⋯S and C-H⋯O hydrogen bonds, forming a chain along the b axis. A short C-H⋯S intramolecular contact is also observed.
