The new ansa-bridged compounds [{Me2C(η<sup>5</sup>-C5H4)(η<sup>2</sup>-C9H6)}M(η<sup>5</sup>-C5H5)Cl], [{(CH2)5C(η<sup>5</sup>-C5H4)(η<sup>2</sup>-C9H6)}M(η<sup>5</sup>-C5H5)Cl](M = Zr, Hf) and [{[Me2C(η<sup>5</sup>-C5H4)(η<sup>3</sup>-C13H8)}Zr(η<sup>5</sup>-C5H5)Cl] show unusual modes of coordination of the indenyl or fluorenyl groups.
