Tetracyclopentadienylzirconium

Conclusions

1.
It was shown by thermogravimetric analysis that tetracyclopentadienylzirconium is stable up to 75°.
2.
On the basis of studying the infrared and NMR spectra it was shown that ligands of the dienic type are absent in the tetracyclopentadienylzirconium molecule, and it was found that all of the protons are equivalent and, consequently, also all of the bonds of the metal-cyclopentadienyl ring in this compound.
