Dalton communications. ansa-Bridged tris(cyclopentadienyl) compounds of zirconium and hafnium: X-ray crystal structures of [M{Me2C(η5-C5H4)2}(η5-C5H5)Cl](M = Zr or Hf)
Abstract
The new ansa-bridged compounds [M{Me2C(η5-C5H4)2}(η5-C5H5)Cl](M = Zr or Hf) have been synthesised and their molecular structures determined by X-ray crystallography. The latter is the first example of a tris(η5-cyclopentadienyl) derivative of hafnium.
