From the tetrahedral coordination of the silicon atom to the trigonal-bipyramidal coordination in (organyl)trifluorosilanes molecules
Abstract
One of the probable causes of the pentacoordination of the silicon atom in the compounds (organyl)trifluorosilanes containing the atom in the pentacoordinated state has been established. The length of the OSi coordination bond included in a five-membered heterocycle depends on the planar state of this cycle. The layered packing of molecules of (cinnamoyloxymethyl)trifluorosilanes ‒ C6H4CH=CHCOOCH2SiF3 ‒ in its crystals was analyzed.
