Abstract
The complete assignment of the resonances of the C-13 NMR spectrum of the 2 ,3,4,5-tetraphenylgermole dianion (Ib) was carried out by 2D NMR spectrosco py. Chemical shifts of ring carbon atoms in the germole dianion in THF solu tion compared with those of uncharged analogs appears to be the result of t he polarization which depends on the negative charge localized on the heter oatom.
