Reaction of ZrS 2 (c lattice parameter 583 pm) with Co( 5 C 5 H 5 ) 2 gives a compound with a c lattice parameter of 1164 pm, and reaction with Co( 5 C 5 Me 5 ) 2 gives a product with a corresponding lattice parameter of 1161 pm ZrS 2 does not react with Fe( 5 C 5 H 5 ) 2 Explain these observations...

The observations can be explained by considering the crystal structures and bonding preferences of t ...

Reaction of ZrS 2 (c lattice parameter 583 pm) with [Co( 5 -C 5 H 5 )

Question:

Reaction of ZrS₂ (c lattice parameter 583 pm) with [Co(η⁵-C₅H₅)₂] gives a compound with a c lattice parameter of 1164 pm, and reaction with [Co(η⁵-C₅Me₅)₂] gives a product with a corresponding lattice parameter of 1161 pm; ZrS₂ does not react with [Fe(η⁵-C₅H₅)₂]. Explain these observations.
