1-(Biphenyl-4-ylmethylidene)thiosemicarbazide monohydrate

Abstract

In the title compound, C14H13N3S.H 2O, the thiosemicarbazide group is nearly planar, with a maximum deviation of 0.072 (2) Å from the ideal least-squares plane, and shows an E conformation. In the crystal packing, the water molecules are involved in an extensive intermolecular N - H⋯O hydrogen-bond network, assisted by O - H⋯S interactions, which link the independent molecules into chains extended along b axis. An intramolecular hydrogen N - H⋯N bond helps to stabilize the molecular conformation.
