It is a white solid that is sparingly soluble in some organic solvents.
While hafnocene is only of academic interest, some more soluble derivatives are precatalysts for olefin polymerization.
Moreso than the Zr analogue, this compound is highly resistant to reduction.
[3] The bis(phosphide) (C5H5)2Hf(PR2)2 can be prepared by salt metathesis from hafnocene dichloride.
