According to the invention a new catalyst precursor is obtained, in which alkoxy or siloxy substitution in the 2-position of 5-membered ring of indenyl compound has been carried out. Thereby a metallocene compound is achieved, in which an oxygen atom is directly bonded to the 2-position of a pentahapto indenyl moiety. The catalyst precursors can be used as components for olefin polymerization catalysts.
