Abstract
The hydrazone ligands 2-acetylpyridine benzoylhydrazone HL1 and 2,6-diacetylpyridinebis(benzoylhydrazone) H2L2 were reacted with Pb(SCN)2, affording [Pb(HL1)(µ-NCS)2] (1) and [Pb(H2L2)(SCN)2] (3), respectively. Recrystallization of 1 or 3 in DMF (or DMSO) produced [Pb(L1)(µ-SCN)] (2) and [Pb(HL2)(NCS)] (4), respectively. Compounds 1–4 were characterized by single crystal X-ray diffraction, Fourier transform infrared spectroscopy and elemental analysis. Compounds 1 and 3 were also characterized by thermogravimetry (with simultaneous differential scanning calorimetry), diffuse reflectance spectroscopy and powder X-ray diffraction. In the solid state, compounds 1, 3 and 4 have shown hydrogen bonds involving the amide hydrogen atoms. Both Pb···N(imine) tetrel bonds and π-stacking interactions were observed in 2 and 4. The thiocyanate/isothiocyanate ligands are responsible for the formation of chains due to Pb···S tetrel bonds in 1 and Pb···N, in 2.
