(E)-N′-[4-(Dimethylamino)benzylidene]-4-hydroxybenzohydrazide hemihydrate
In the title compound, C(16)H(17)N(3)O(2)·0.5H(2)O, the two hydrazide mol-ecules are approximately planar: the dihedral angles between the two substituted benzene rings are 7.7 (2) and 4.2 (2)°. Both hydrazone mol-ecules exist in a trans geometry with respect to their methyl-idene units. In the crystal, the water mol-ecule lies between the two organic mol-ecules and makes bifurcated O-H⋯(N,O) h...

متن کامل(E)-4-Methoxy-N′-(2,4,5-trimethoxybenzylidene)benzohydrazide hemihydrate
The title compound crystallizes as a hemihydrate, C18H20N2O5·0.5H2O. The mol-ecule exists in an E conformation with respect to the C=N imine bond. The 4-meth-oxy-phenyl unit is disordered over two sets of sites with a refined occupancy ratio of 0.54 (2):0.46 (2). The dihedral angles between the benzene rings are 29.20 (9) and 26.59 (9)°, respectively, for the major and minor components of the 4...
متن کاملN-Methyl-4-(4-pivalamidophenylsulfanyl)picolinamide hemihydrate
In the title compound, C(18)H(21)N(3)O(2)S·0.5H(2)O, the benzene ring makes dihedral angles of 88.59 (6) and 40.74 (8)° with the pyridine ring and the amide group, respectively. The water O atom lies on a twofold axis. In the crystal, the organic mol-ecules and the water mol-ecules are linked via O-H⋯O hydrogen bonds, while the organic mol-ecules are connected to each other via N-H⋯O hydrogen b...
متن کاملN-(4-Aminophenyl)-1,8-naphthalimide hemihydrate
The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds. There are π-π stacking inter-actions [centroid-centroid distances of 3.718 (2), 3.510 (2) and 3.546 (2) Å] and C-H⋯π inter-actions between the mol-ecules. The water mol...
