Abstract

Metal complex containing one or more silsesquioxane ligands, having the formula Zy(MAxBq)b (I), wherein Z is a silsesquioxane according to the formula R7-lSi7O12YD1+l (II), M is a metal from groups 3-6 of the Periodic System of the Elements and the lanthanides, A is a monoanionic ligand bound to the metal, B is a pi-bound ligand, y represents the number of silsesquioxane ligands and is 1-10, b represents the number of metal groups and is 1-20, q is 0, 1 or 2, x is the number of substituents A bound to the metal; the value of x depends on the metal used and is equal to the valency of the metal minus 1, 2, 3 or 4, R is a substituent bound to Si, Y is an atom from group 13 or 14 of the Periodic System of the Elements, D is a group, directly bound to Y or Si with one atom from group 15 or 16 of the Periodic System of the Elements and l determines the amount of substituents R and atoms D and is equal to 0, 1, 2 or 3.
