Synthesis and crystal structure of 1-(4-fluorophenyl)-and 1-(4-dimethylamino)phenylgermatranes

The X-ray crystal structure of 1-(4-fluorophenyl)-and 1-(4-dimethylaminophenyl)germatranes reveals that the germanium atom is pentacoordinated and adopts a trigonal bipyramidal geometry. The fluorophenyl and dimethylaminophenyl groups and the nitrogen atom each occupy an apical position with the transannular N→Ge bond of 2.192(3) and 2.249(3) Å; the deviation of the Ge atom from the O(2)-O(8)-O(9) plane is 0.2306(4) and 0.2693(3) Å, correspondingly. __________ Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 776–781, May, 2008.
