New oligogermane with a five coordinate germanium atom: the preparation of 1-germylgermatrane

Dalton Trans. 2014 May 14;43(18):6605-9. doi: 10.1039/c3dt53523a.

Abstract

The first example of an oligogermane, N(CH2CH2O)3Ge-Ge(SiMe3)3 (1), containing a hypercoordinate germanium atom was prepared and characterized by various methods (NMR, UV/vis, and X-ray analysis). The electronic structure of compound 1 was investigated via DFT calculations.
