title: (E)-Methyl N'-[(1H-indol-3-yl)methyl-idene]hydrazinecarboxyl-ate 0.25-hydrate.
abstract: The asymmetric unit of the title compound, C(11)H(11)N(3)O(2)·0.25H(2)O, contains two independent organic mol-ecules and a water mol-ecule, which lies on a twofold rotation axis. The side chains of the two mol-ecules have slightly different orientations, the C=N-N-C torsion angle being -163.03 (15)° in one and -177.52 (14)° in the other, with each adopting a trans configuration with respect to the C=N bond. In the crystal, mol-ecules are linked into chains extending along b by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and in addition, four inter-molecular C-H⋯π inter-actions are present.
