Convenient salt metathesis reaction of the N-heterocyclic germanium(II) nucleophile LGeK(Et(2)O)(2) [L = C(Me)CHC(Me)N(2,6-(i)Pr(2)C(6)H(3))] with the beta-diketiminato Ge(II) chloride L'GeCl [L' = CH{CMe(NR)}(2), R = 2,6-(i)Pr(2)C(6)H(3)] and the tin analogue L'SnCl furnishes the corresponding novel digermylene having a Ge(I)-Ge(I) bond and the first germylene-stannylene 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) sigma bonds with ionic character.
N-杂环锗（II）亲核试剂LGeK(Et(2)O)(2) [L = C(Me)CHC(Me)N(2,6-(i)Pr(2)C(6)H(3))] 与β-二酮亚胺基锗（II）氯化物L'GeCl [L' = CH{CMe(NR)}(2), R = 2,6-(i)Pr(2)C(6)H(3)] 以及锡类似物L'SnCl发生便捷的复分解反应，分别生成了具有Ge（I）-Ge（I）键的相应新型二锗烯和具有Ge（I）-Sn（I）键的首个锗烯-亚锡烯；对后一种化合物的光谱、结构和理论分析表明，它们具有具有离子特性的Ge-M（M = Ge和Sn）σ键。
