Reaction of the monoanionic radical salt IP˙⁻K⁺ (IP = (Py)CH(=NR); Py = C₅H₄N, R = 2,6-iPr₂C₆H₃; α-iminopyridine) with GeCl₂(dioxane) afforded compound (IPGeCl)₂ (1) which produced red blocks of IPGe: (2), when treated with KC₈ in toluene. 1 is a digermylene formed via C–C coupling between two carbon-centered radicals. 2 can be considered as an analogue of a N-heterocyclic carbene, which exhibits a five-membered GeC₂N₂ ring with one C=C double bond. 2 is formed by two-electron reduction of 1 with cleavage of the two Ge–Cl bonds and the central C–C single bond.
