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