摘要：

3-Formyl- and 3-acetylpyridine N(4)-methylthiosemicarbazone, H3Fo4M and H3Ac4M, respectively, have been prepared, their. structures solved and IR, NMR :md UV spectra recorded. Intramolecular and intermolecular hydrogen bonding are both present, but the mode of the intermolecular interaction is different in the two compounds. Further, there is a significant difference in their angles between the mean planes of the pyridine ring and thiosemicarbazone moiety. The H-1 NMR spectral studies show significant differences between the two. (C) 2000 Elsevier Science B.V. All rights reserved.
