ATRANES. II. DIPOLE MOMENTS AND STRUCTURE OF SILATRANES

Abstract

Possible steric configurations of 1-organyl- and 1-organoxysilatranes, , are considered. The dipole moments of six compounds of this type (X=CH₃, (CH₃)₂CH, CH₂=CH, C₆H₅, C₂H₅O, C₆H₅O) have been found experimentally to be extremely high, 5.3–7.1 D. They conclusively show that the silatranes contain a semipolar transannular coordinate bond Si←N between the negatively charged 5 -covalent silicon atom in the middle of the planar SiO₃ group and the tetrahederal onium nitrogen atom.
