On the experimental–theoretical discrepancy regarding the silicon–carbon double bond length
Abstract
Ab initio calculations show that the CSi bond length of 1.764 Å in (Me3Si)2Si
C(adamantyl)(OSiMe3)is electronically elongated (mainly by OSiMe3)and that the unperturbed r(c
Si) is ca. 1.70 Å much chorter than the 1.832 Å measured by electron diffraction.
