Fig. 5: Molecular structure of compound 3 in a crystalline state.
From: Neutral 4π-electron tetrasilacyclobutadiene contains unusual features of a Möbius-type aromatic ring

The anisotropic displacement parameters are depicted at the 50% probability level. Hydrogen atoms as well as disordered parts of the molecule are omitted for clarity. Symmetry code A: 3/2-x, 3/2-y, 1-z.
