Summary
| Description |
Ball-and-stick model of the disilene molecule, Si2H4. The structure depicted is the trans-bent isomer (C2h point group, 1Ag symmetry), H2Si=SiH2, reported to be the lowest energy isomer of Si2H4. Precise molecular structural parameters are hard to find but the overall connectivity, symmetry and coarse geometry are described in J. Chem. Phys. (2006) 124, 074303 and Chem. Phys. Lett. (2008) 466, 11-15. A rationale for the geometry involving π-σ* orbital mixing is given in Proc. Jpn. Acad. Ser. B Phys. Biol. Sci. (2012) 88, 167-191. R2Si=SiR2 bond lengths in the CSD are typically around 2.2 Å. See, for example, CIJRAO from Organometallics (1984), 3, 793-800. Colour code:
