The carbon-carbon bond length of coordinated ethylene in Ti(15-C5Me5)2(1²-C2H4) is 1.44 A, as determined by X-ray crystal structure analysis. Computational quantum mechanical modelling of the reactive intermediate [Ti(n5-Cp)₂Me(n²-C2H4)]* gives a carbon- carbon bond length of 1.34 Å for the coordinated ethylene ligand. Rationalise this difference in bond length. Sketch relevant molecular orbitals. (CsMes = pentamethylcyclopentadienyl)

The carbon-carbon bond length of coordinated ethylene in
Ti(15-C5Me5)2(1²-C2H4) is 1.44 A, as determined by X-ray crystal
structure analysis. Computational quantum mechanical modelling of
the reactive intermediate [Ti(n5-Cp)₂Me(n²-C2H4)]* gives a carbon-
carbon bond length of 1.34 Å for the coordinated ethylene ligand.
Rationalise this difference in bond length. Sketch relevant molecular
orbitals. (CsMes = pentamethylcyclopentadienyl)
