The reaction between SnCl2 and two equivalents of (Dep2P)Li at low temperature gave the bis(phosphanyl)stannylene {(Dep)2P}2Sn (4Sn), although this compound decomposes in solution at room temperature (Dep = 2,6-Et2C6H3). Compound 4Sn is monomeric in the solid state and exhibits significant Sn…Ar contacts, which mitigate the electron deficiency of the Sn center. In contrast, the reaction between GeCl2(1,4-dioxane) and two equivalents of (Tep2P)Li gave the digermene (Tep2P)2Ge.Ge(PTep2)2 (5Ge; Tep = 2,4,6-Et3C6H2). Compound 5Ge crystallizes as a strongly trans-bent and twisted digermene; however, in solution, variable-temperature 31P{1H} and 1H diffusion-ordered NMR spectroscopy reveal a dynamic equilibrium between the germylene and digermene forms of 5Ge.
