Synthesis and study of coordinating agents for the synthesis of new coordination compounds

Two compounds were obtained from the condensation reaction of semicarbazide (hydrazinecarboxamide) and semithiocarbohydrazide (hydrazinecarbothioamide) compounds with a 3-pyridinecarboxaldehyde carbonyl compound: (E)-1-(pyridin-3-ylmethylene)thiourea (L-1) and (E)-1-(pyridin-3-ylmethylene)urea (L-1) (L-2). The structure and composition of these compounds were determined using theoretical calculations with the GAMESS software package and IR spectroscopy. The new organic molecules L-1 and L-2 have the potential to be used as mono- or bidentate coordinating agents in the construction of coordination compounds with various useful properties.
