N′-[(E)-4-Benzyloxy-2-hydroxybenzylidene]-4-nitrobenzohydrazide monohydrate
The title compound, C(21)H(17)N(3)O(5)·H(2)O, exists in the keto form with an E conformation with respect to the azomethine double bond. The twist angles between the aromatic rings are in the range 4.67 (10)-17.54 (10)°. A water mol-ecule of solvation is present in the lattice. A conventional intra-molecular O-H⋯N hydrogen bond increases the rigidity of the mol-ecule. Inter-molecular O-H⋯O, N-H...
متن کامل(E)-4-Hydroxy-N′-(2-hydroxy-4-methoxybenzylidene)benzohydrazide monohydrate
The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·H(2)O, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is almost planar (r.m.s. deviation for all non-H atoms = 0.040 Å). The amido N atom is the hydrogen-bond donor to the water mol-ecule, which is the hydrogen-bond donor to the hydr-oxy groups of two neighboring mol-ecules. One of the ...
متن کاملN-(4-Chlorophenyl)-2-(8-quinolyloxy)acetamide monohydrate
In the title compound, C(17)H(13)ClN(2)O(2)·H(2)O, the dihedral angle between the quinoline ring system and the benzene ring is 13.0 (1)°. An intra-molecular N-H⋯O hydrogen bond may influence the mol-ecular conformation. In the crystal structure, acetamide mol-ecules are linked to water mol-ecules via inter-molecular O-H⋯ N and N-H⋯O hydrogen bonds and in turn linked into chains along [010] via...
متن کامل(E)-N′-(5-Chloro-2-hydroxybenzylidene)-4-(8-quinolyloxy)butanohydrazide monohydrate
The crystal of the title Schiff base compound, C(20)H(18)ClN(3)O(3)·H(2)O, was twinned by a twofold rotation about (100). The asymmetric unit contains two crystallographically independent mol-ecules with similar conformations, and two water mol-ecules. The C=N-N angles of 115.7 (6) and 116.2 (6)° are significantly smaller than the ideal value of 120° expected for sp(2)-hybridized N atoms and th...
متن کاملN′-[(E)-4-Bromobenzylidene]-1-benzofuran-2-carbohydrazide monohydrate
The title compound, C(16)H(11)BrN(2)O(2)·H(2)O, exists in a trans conformation with respect to the N=C bond [1.2815 (14) Å] and the benzofuran ring system forms a dihedral angle of 2.96 (5)° with the benzene ring. In the crystal, the ketone O atom accepts two O-H⋯O and one C-H⋯O hydrogen bond, and the water O atom accepts an N-H⋯O inter-action. Together, these lead to infinite layers lying para...
