The syntheses of the triazenide complexes [{N­(NDipp)2}2M] (Dipp = 2,6-di-isopropylphenyl; M = Ge­(II) (1), Sn­(II) (2), Pb­(II) (3), and Te­(II) (5)) are described for the first time. These compounds have been characterized by single-crystal X-ray diffraction and heteronuclear NMR spectroscopy. Density functional theory calculations were employed to confirm the presence and nature of the stereochemically active lone pairs in 15, alongside the Gibbs energy changes for their general synthesis, which enable the rationalization of observed reactivities.
