3,3-Dimethyl-1-oxa-3-silacyclopentane was synthesized and its molecular structure was determined by gas phase electron diffractometry using ab initio calculations (GAUSSIAN-92, RHF method, 6-31G* basis set). The six models derived from the gas phase electron diffraction analysis equally adequately (R similar to 3%) describe experimental data, whereas quantum chemical calculations lead to only one (O-envelope) conformer. The stereochemical data and the results of ab initio calculations confirm that the O-envelope is the best conformation; its geometrical parameters are as follows (bond lengths r(a) in Angstrom, and angles in degrees; total error in parentheses in units of the least significant digit): r(Si-C-cyc) 1.891(3) and 1.904; r(Si-C-Me) 1.877 and 1.879; r(C-C) 1.556(7); r(C-O) 1.431(3) and 1.445; r(C-cyc-H) 1.11(2); r(C-Me-H) 1.10(2); phi(O-C-C-Si) -33.0(14); angle CcycSiCcyc 92.2(5); angle CMeSiCMe 107.2(8); angle SiCC 102.6(6); angle CCO 109.9(11); angle HCcycH 110.5(47); angle SiCMeH 111.6(14). Method for the synthesis of 3,3-dimethyl-1-oxa-3-silacyclopentane is given, and generalized notation for five-membered ring confor- mations is suggested.
