Metallocene Hydrides: Their Didactic Value for Teaching Organometallic Chemistry

CHIMIA
Metallocene hydrides, Cp2MHn (n=1-3), are complexes known for elements of Groups 3 to 8. Their properties can be understood by the use of a common qualitative MO diagram.

A Comprehensive Solution and Solid-State NMR Study of Proton Spin Lattice Relaxation in Paramagnetic Metallocenes

Physchem
Solid solutions of the metallocenes ferrocene (Cp2Fe), nickelocene (Cp2Ni), and cobaltocene (Cp2Co) have been prepared by manually grinding the components together, or by co-crystallizing them from solution.
