Trigermaallene and 1,3-Digermasilaallene

X-ray analysis of the first trigermaallene (3) and 1,3-digermasilaallene (4) revealed that the trimetallaallene skeletons are not linear but significantly bent, similarly to the corresponding trisilaallene 2. In contrast to 2, no dynamic disorder was observed for 3 and 4.
