Abstract
2-Benzoylpyridine piperidinyl- and hexamethyleneiminylthiosemicarbazon es, HBzpip and HBzhexim, respectively, crystallize in a hydrogen bonde d Z isomeric conformation with respect to the C7-N2 bond. The intramol ecular hydrogen bond is between N3-H...N1, but the S atom is E to the azomethine nitrogen, N2, for HBzpip and Z for HBzhexim. HBzpip is the second ZE isomer known, but the first that does not have a formal hydr ogen bond to N2.
