摘要

A new thiosemicarbazone, HL is synthesized from di-2-pyridyl ketone and 4-phenyl-3- thiosemicarbazide and structurally and spectrochemically characterized. 1H NMR, 13C NMR, COSY, HMQC and IR spectra of the compound are studied and the proton magnetic resonance spectrum reveals some unprecedented observations. The thione form is predominant in the solid state, as supported by the crystal structure and IR data, while a ...
