The crystal structures of two hypervalent silicon compounds (N -> Si)
(2-benzothiazolylthiomethyl)trifluorosilane and (N -> Si) (2-benzoxazo
lylthiomethyl)trifluorosilane have been determined. Both molecules hav
e similar geometrical parameters. The Si atom acquires a distorted tri
gonal bipyramidal penta-coordination due to five-membered ring closure
by a donor-acceptor N -> Si bond of lengths of 1.988(3) and 1.967(4)
Angstrom, respectively. In the second crystal structure, molecules for
m a stacked packing with the distance between the planar parts of the
neighbouring molecules in the stacks equal to 3.45 Angstrom.
