Semicarbazones can exist in two tautomeric forms. In the solid state, they are found in the keto form. This work presents the synthesis, structures and spectroscopic characterization (IR and NMR spectroscopy) of four such compounds, namely the neutral molecule 4-phenyl-1-[phenyl(pyridin-2-yl)methylidene] semicarbazide, C19H16N4O, (I), abbreviated as HBzPyS, and three different hydrated salts, namely the chloride dihydrate, C19H17N4O+center dot Cl-center dot 2H(2)O, (II), the nitrate dihydrate, C19H17N4O+center dot NO3-center dot 2H(2)O, (III), and the thiocyanate 2.5-hydrate, C19H17N4O+center dot SCN-center dot 2.5H(2)O, (IV), of 2-[phenyl({[(phenylcarbamoyl) amino]imino})methyl]pyridinium, abbreviated as [H(2)BzPyS](+)center dot X-center dot nH(2)O, with X = Cl- and n = 2 for (II), X= NO3- and n = 2 for (III), and X = SCN- and n = 2.5 for (IV), showing the influence of the anionic form in the intermolecular interactions. Water molecules and counter-ions (chloride or nitrate) are involved in the formation of a two-dimensional arrangement by the establishment of hydrogen bonds with the N-H groups of the cation, stabilizing the E isomers in the solid state. The neutral HBzPyS molecule crystallized as the E isomer due to the existence of weak pi-pi interactions between pairs of molecules. The calculated IR spectrum of the hydrated [H(2)BzPyS](+) cation is in good agreement with the experimental results.
