Germanium dichloride dioxane is a chemical compound with the formula GeCl2(C4H8O2), where C4H8O2 is 1,4-dioxane. It is a white solid. The compound is notable as a source of Ge(II), which contrasts with the pervasiveness of Ge(IV) compounds. This dioxane complex represents a well-behaved form of germanium dichloride.
It is prepared by reduction of a dioxane solution of germanium tetrachloride with tributyltin hydride: [2]
Hydrosilanes have also been used as reductants. [3]
The complex has a polymeric structure. Germanium adopts an SF4-like shape with cis Cl ligands (Cl-Ge-Cl angle = 94.4°) and axial positions occupied by oxygen provided by a bridging dioxane. The Ge-O and Ge-Cl distances are 2.40 and 2.277 A, respectively. [4]
The complex is used in the preparation of organogermanium compounds. [5] [6] In organic synthesis, the complex is used as a Lewis acid with reducing properties. [3]
