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.
