The structure of 1-(trifluoromethyl)germatrane

1-(Trifluoromethyl)germatrane (CF3Ge(OCH2CH2)(3)N) has been prepared from C F3Ge(OCH3)(3) and triethanolamine and characterized by NMR, vibrational, an d mass spectroscopy. The compound crystallizes in the monoclinic space grou p P2(1)/n with a = 785.73(6), b = 1257.8(1), c = 999.92(9) pm, beta = 90.87 1(7)degrees, and Z = 4. The equatorial Ge-O bond lengths of the almost perf ect trigonal bipyramid average to 178.7(3) pm, whereas the axial Ge-C bond length is 200.6(2) pm. The transannular Ge-N contact (210.8(2) pm) is consi derably shorter than in other organylgermatranes.
