The molecular orbitals of the known complex ,the fragment ,and cyclo–P₅^- have been calculated.

a. Compare the orbital interactions between d orbitals of Ti and P₅^- orbitals with the corresponding interactions between d orbitals of Fe and cyclopentadiene ( Figure 13.28 ) .

b. Of the species , and P₅^- which has the longest P–P distance? Why? (See Z.-Z. Liu, W.-Q. Tian, J.-K. Feng, G. Zhang, W.-Q. Li, J. Phys. Chem. A , 2005 , 109 , 5645.)
