In the trigonal‐bipyramidal species H 2 CSF 4 (1) the H atoms are located in the plane of the axial F atoms (low‐temperature crystal structure analysis, electron diffraction). The PE spectrum confirms that the resonance structure having a double bond has greater weight than in other ylides. (1) is exceptionally stable thermally, but highly reactive (addition to the polar CS bond, CH 2 transfer).
