Abstract

Convenient salt metathesis reaction of the N-heterocyclic germanium(II) nucleophile LGeK(Et2O)2 [L = C(Me)CHC(Me)N(2,6-iPr2C6H3)] with the β-diketiminato Ge(II) chloride L′GeCl [L′ = CH{CMe(NR)}2, R = 2,6-iPr2C6H3] and the tin analogue L′SnCl furnishes the corresponding novel digermylene having a Ge(I)–Ge(I) bond and the first germylenestannylene with a Ge(I)–Sn(I) bond, respectively; spectroscopic, structural and theoretical analysis of the latter compounds revealed that they bear Ge–M (M = Ge and Sn) σ bonds with ionic character.
