Terphenyltin and terphenylgermanium trihydrides were deprotonated in reaction with strong bases, such as LiMe, LDA, or KBn. In the solid state, the Li salts of the germate anion4and4aexhibit a Li–Ge contact. In the Li salt of the dihydridostannate anion6a, the Li cation is not coordinated at the tin atom instead an interaction of the Li cation with the hydride substituents was found. Evidenced by1H–7Li-HOESY NMR spectroscopy the Li-salt of the deprotonated tin hydride6aexhibits in toluene solution a contact between Li cation and hydride substituents, whereas in the1H–7Li-HOESY NMR spectrum of the homologous germate salt4a, no crosspeak between hydride and Li signals was found. The organodihydridogermate and -stannate react as nucleophiles with low-valent Group 14 electrophiles. Thus, three compounds were synthesized: Ar–Ë′–EH2–Ar (E′, E = Sn, Ge; Pb, Ge; Pb, Sn; Ar = Ar′, Ar*). Following an alternative synthesis Ar′SnH2PbAr* was synthesized in reaction between [(Ar*PbH)2] and [(Ar′SnH)4] generated in situ. In reaction between low-valent organotin hydride [(Ar*SnH)2] and organdihydridostannate [Ar*SnH2]−formation of distannate [Ar*2Sn2H3]−was found.
