1-(Trifluoromethyl)silatrane, CF3Si(OCH2CH2)(3)N, was prepared from CF3Si(OCH3)(3) and triethanolamine and characterized by NMR, vibrational, and mass spectroscopy. The compound crystallizes in the monoclinic space group P2(1)/n with a = 777.2(1), b = 1236.9(2), c = 1002.8(1) pm, beta = 91.33(1)degrees, Z=4. The equatorial Si-O bond lengths of the almost perfect trigonal bipyramid average 165.3(2) pm, the axial Si-C bond length is 94.6(1) pm. The transannular Si-N contact, 202.4(1) pm, is considerably shorter than in other organylsilatranes.
