Redetermination of the Germanium Dichloride Complex with 1,4-Dioxane at 173K

The structure of germanium dichloride–1,4-dioxane (1/1), GeCl₂[C₄H₈O₂], (1), has been redetermined at 173 K and refined in space group C2/c, rather than Cc which was used in the original determination by Kulishov, Bokii, Struchkov, Nefedov, Kolesnikov & Perl'mutter [Zh. Strukt. Khim. (1970), 11, 61–64]. The data from the original determination had already been used to redetermine the structure of (1) in the revised space group C2/c [Marsh (1997). Acta Cryst. B53, 317–322] but here we present a more accurate structure determination using new data. The Ge—Cl bond length is 2.2813 (5) Å. The structure consists of infinite chains of alternating GeCl₂ and C₄H₈O₂ molecules with a Ge...O distance of 2.399 (1) Å.
