✦ Synopsis

cyclodisilazane / Structure elucidation / Electron diffraction The syntheses or 1,3-di-tert-butyl-2,2,4,4-tetrachlorocyclodi-bered rings and nearly planar configurations at the nitrogen silazane (3) and of di-tert-butyl-2,2,4,4-tetrafluorocyclod~s~1d-atoms. The Si-N bond lengths are 171.1(1) pm and 170.6(3) zane (4) are reported. The X-ray crystal structure of 3 and pm and the Si...Si transannular distances 245.0(1) and the electron-diffraction gas-phase structure of 4 have been 241.3(13) pm in 3 and 4, respectively.
