Preparation and X-ray structure of [Ge{N(SiMe3)2}2(µ-O)]2, a rare 1,3-cyclodigermoxane
Abstract
Exposure of the monomeric germanium silylamide Ge[N(SiMe3)2]2 to molecular oxygen generates the unusual crystalline digermoxane [Ge{N(SiMe3)2}2(µ-O)]2, characterised by NMR spectroscopy and X-ray crystallographic data [Ge–O(av.) 1.805(9)Å; O–Ge–O(av.) 87.5(4), Ge–O–Ge(av.) 92.5(4)°].
