(E)-N′-(4-Pyridylmethylene)-4-(8-quinolyloxy)butanohydrazide 0.25-hydrate
The asymmetric unit of the title compound, C(19)H(18)N(4)O(2)·0.25H(2)O, contains two organic molecules and a solvent water molecule with 50% occupancy. The two molecules differ in their conformations: in one molecule it is (+)gauche-trans-trans-(+)gauche-trans, whereas in the other it is (−)gauc...

description | The asymmetric unit of the title compound, C(19)H(18)N(4)O(2)·0.25H(2)O, contains two organic molecules and a solvent water molecule with 50% occupancy. The two molecules differ in their conformations: in one molecule it is (+)gauche-trans-trans-(+)gauche-trans, whereas in the other it is (−)gauche-trans-trans-(−)gauche-trans. The dihedral angles between the pyridine ring and the quinoline ring system are 67.4 (3) and 68.0 (2)°. Molecules are linked into a supramolecular two-dimensional array via N—H⋯N hydrogen bonds, with each partially occupied water molecule connected via an O—H⋯O hydrogen bond. C—H⋯O interactions are also present. |
