Steric effects do not account for the stability of compounds like 1 , which contain a planar four‐coordinate carbon atom; rather the electronic interaction of the low‐lying empty Zr 4d orbitals with a high‐lying σ orbital of the distorted ethylene unit is the primary stabilizing effect. This is the result of calculations with a minimal basis set on model systems. X = H, Cl.
