New germanium dichloride complexes

Tuning Philicity of Dichlorosilylene: Nucleophilic Behavior of the Dichlorosilylene–NHC Complex Cl2Si–IPr

“…7 However, n-donor ligands can and do readily and effectively stabilize the low-coordinate germanium center, and accordingly, a range of dichlorogermylene complexes with such n-donor ligands was successfully prepared long ago. 8 Among them, by far, the most common and readily available is the complex of dichlorogermylene with 1,4-dioxane (diox), [Cl 2 Ge–diox]. 9…”

“…The germanium analogue of dichlorosilylene, namely, dichlorogermylene Cl 2 Ge:, also could not be isolated as a room temperature-stable derivative because of its exceptionally high reactivity including a polymerization process . However, n-donor ligands can and do readily and effectively stabilize the low-coordinate germanium center, and accordingly, a range of dichlorogermylene complexes with such n-donor ligands was successfully prepared long ago . Among them, by far, the most common and readily available is the complex of dichlorogermylene with 1,4-dioxane (diox), [Cl 2 Ge–diox] …”
