Abstract
The first examples of pyrene-fused Janus-type N-heterocyclic germylenes (NHGe) are reported. Remarkably, the pyrene linker and the germanium containing rings are extremely twisted, with “twist angles” up to 64°. Coordination of a Lewis base modifies the twisting of pyrene to an overall bent core (141° bend angle).
