Bis(chlorotetrylene)s of Si, Ge, and Sn have been synthetically realized starting from the backbone‐bridged bis(amidine) 1 . Double deprotonation of 1 and subsequent reaction with trichlorosilane affords the bis(dichorosilane) 2 , which is converted to the respective bis(chlorosilylene) 3 by dehydrochlorination using lithium bis(trimethylsilyl)amide. The related bis(chlorogermylene) 4 and the bis(chlorostannylene) 5 are obtained by reacting the dilithium salt with GeCl 2 ⋅ (dioxane) and SnCl 2 , respectively. 2 readily reacts with benzil affording the bis(siladioxolene) 6 , while no reaction was observed when using the bis(chlorogermylene) 4 . The complexes have been fully characterized and their molecular solid‐state structures have been investigated by means of single‐crystal X‐ray diffraction analysis.
