Patent ID: 7691984

Claim:
A metal containing complex represented by the structures selected from the group consisting of: wherein M is a metal group having a valence of from 2 to 5 wherein R 1 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl, having from 1 to 10 carbon atoms; R 2 is selected from the group consisting of hydrogen, alkyl, alkoxy, cycloaliphatic, and aryl; R 3 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl; R 4 is a C3-10 branched alkylene bridge having at least one chiral carbon atom; R 5-6 are individually selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, aryl, and heterocyclic containing either oxygen, or nitrogen atoms; n is an integer equal to the valence of the metal M; wherein M is a metal ion selected from Group 4 and 5 metals; wherein R 1 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl, having from 1 to 10 carbon atoms; R 2 is selected from the group consisting of hydrogen, alkyl, alkoxy, cycloaliphatic, and aryl; R 3 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl; R 4 is a C3-10 branched alkylene bridge having at least one chiral carbon atom; R 5-6 are individually selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, aryl, or heterocyclic containing an oxygen, or nitrogen atom; R 7 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl; and wherein m and n are at least 1 and the sum of m plus n is equal to the valence of the metal M.
