| Abstract: | The geometric structures of seleno- and thiocarbonyl difluoride, Se=CF2 and S=CF2, studied in the gas phase by electron diffraction, are presented. For S=CF2 the electron diffraction data are combined with microwave rotational constants. The following geometric parameters were derived: for SeCF2 (rα0 values) Se-C = 1.743(3) Å, C-F = 1.314(2) Å and ? FCF = 107.5(0.4)° ; for SCF2 (rav values) S-C = 1.589(2) Å, C-F = 1.316(2) Å and FCF = 107.1(0.2)° . Uncertainties are 3σ values of the least squares analyses. |
