New Intracomplex Compoundsof Pentacoordieate Germanium. Hypogermatranes5Ge-Substituted (N→Ge) 2-Oxa-5-aza-1-germacydopentanes

摘要

The chemistry of intracomplex compounds of penta-coordinate germanium, germatranes XGe(OCH2CH2)3N, containing the transannular coordination bond N→Ge, has begun in 1968 and continues to actively develop [1-4]. In the present century, a great attention was attracted by their bicyclic analogs, quasigermatranes X2Ge(OCH2CH2)2NH [5, 6].
