Abstract: The unit cell structure of 1-acetyl-3-thiosemicarbazide (ATSC) and the types of hydrogen bonds present in crystalline form are envisaged from single crystal X-ray diffraction studies. The presence of four types of hydrogen bonds in crystal packing is evident (N─H• • •O, N─H• • •N, N─H• • •S and O─H• • •O) from the results obtained in present study. The topological analysis of hydrogen bonds indicated both inter- and intramolecular hydrogen bonding. Presence of water molecule is evident in its structure indicating that the title compound is in hydrated form. The single crystal X-ray diffraction data corresponding to hydrogen bonding reveals the hydrogen-bond strength sequence as: N─H• • •N > O─H• • •O > N─H• • •O > N─H• • •S.
