    Description / Table of Contents: Zusammenfassung.  1-(Trifluoromethyl)silatran, CF3Si(OCH2CH2)3N, wurde aus CF3Si(OCH3)3 und Triethanolamin gewonnen und durch NMR-, Schwingungs- und Massenspektroskopie charakterisiert. Die Verbindung kristallisiert in der monoklinen Raumgruppe P21/n mit a=777.2(1), b=1236.9(2), c=1002.8(1) pm, β=91.33(1)°, Z=4. Die equatorialen Si*O-Abstände der nahezu perfekten trigonalen Bipyramide betragen im Schnitt 165.3(2) pm, der axiale Si*C-Abstand 194.6(1) pm. Der transanulare Si*N-Kontakt, 202.4(1) pm, ist beträchtlich kürzer als in anderen Organylsilatranen.
    Notes: Summary.  1-(Trifluoromethyl)silatrane, CF3Si(OCH2CH2)3N, was prepared from CF3Si(OCH3)3 and triethanolamine and characterized by NMR, vibrational, and mass spectroscopy. The compound crystallizes in the monoclinic space group P21/n with a=777.2(1), b=1236.9(2), c=1002.8(1) pm, β=91.33(1)°, 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.
