HOE 88/F 384 Abstract of the disclosure: Bisindenyl derivate, and a process for the preparation thereof. A bisindenyl derivate of the formula I Image (I) (M1 = Si or Ge, R6 and R7 = unsubstituted or substituted indenyl radical) is obtained in very good yield by reacting a compound of the formula II Image (II) (X = halogen) with a compound of the formula III or IV R6 - M2 (III) R7-M2 (IV) (M2 = alkali metal) if, in the reaction, compound III or IV is added slowly to compound II.
