Concurrent agostic and tetrel bonding interactions in lead(II) complexes with an isonicotinohydrazide based ligand and several anions

In this manuscript we report for the first time the concurrent agostic and tetrel bonding interactions involving the heaviest tetrel atom (Pb) in N'-(phenyl(pyridin-2-yl)methylene)isonicotinohydrazide-PbX complexes (X = Cl, I, NCS, NO2).
