2′-(3-Hydroxybenzylidene)pyrazine-2-carbohydrazide monohydrate
The title compound, C(12)H(10)N(4)O(2)·H(2)O, was synthesized by the reaction of pyrazine-2-carboxylic acid hydrazide and 3-hydroxy-benzaldehyde in ethanol. In the crystal structure, the organic mol-ecules are linked into extended chains by inter-molecular N(amide)-H⋯O(hydr-oxy) hydrogen bonds. Additional hydrogen bonds between the water mol-ecule and three adjacent organic mol-ecules, as well ...

Single crystals of the title compound, C(16)H(14)N(2)O(5)·H(2)O, were obtained from a condensation reaction of 1,3-benzodioxole-5-carbohydrazide and 3-methoxy-salicylaldehyde in a 95% ethanol solution. The asymmetric unit consists of a Schiff base mol-ecule, which assumes an E configuration with respect to the C=N bond, and a water mol-ecule of crystallization. The dihedral angle between the tw...

In the title compound, C(13)H(9)N(3)O(2)·H(2)O, the dihedral angle between the aromatic rings is 10.7 (4)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, the components are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds.
متن کاملN′-[(E)-2-Hydroxy-5-iodobenzylidene]furan-2-carbohydrazide monohydrate
The organic mol-ecule of the title monohydrate, C(12)H(9)IN(2)O(3)·H(2)O, features a disordered furyl ring with the major component [site occupancy = 0.575 (18)] having the carbonyl O and furyl O atoms syn, and the other conformation having these atoms anti. The mol-ecule is slightly twisted with the dihedral angle between the benzene and furyl rings being 10.3 (6)° (major component). An intra-...
