To explore the reactivity of divalent metallylene, the non-innocent ligand supported germylene and stannylene were successfully synthesized. The non-innocent ligand supported germanium compound can be viewed as a pyridine annulated N-heterocyclic germylene or a neutral α-iminopyridine coordinated germylone. The Ge-ligand cooperation was observed in the reaction of germylene with HCl and BCl3, confirming the presence of a vacant p orbital at the Ge(II) atom. The readily transferring of the ligand from germylene to MCl­­2 (M = Ge, Sn) with the extrusion of metallic germanium reflects the electron richness of the central Ge(0) atom. The germylone character was further verified via four-electron oxidation with two equivalents of tetra-chloro-o-benzoquinone to give six-coordinated germanium (IV) adduct. Besides, pyridine-coordinated diamido stannylene was also prepared from transamination of corresponding α-aminopyridine ligand with Sn[N(TMS)2]2. The coordination chemistry of stannylene with [RuCl2(η6-cymene)]2 was investigated.
