Patent ID: 7947814

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; 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 an alkylene bridge; R 5-6 are individually selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, aryl, and heterocyclic containing either oxygen, or nitrogen atoms; and 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; 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 an alkylene bridge; 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; m and n are at least 1 and the sum of m plus n is equal to the valence of the metal M; and, wherein M is an alkaline earth metal; R 1 is selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, and aryl, having from 1 to 10 carbon atoms; R 2-3 are individually selected from the group consisting of hydrogen, alkyl, alkoxy, cycloaliphatic, and aryl; R 4-5 are individually C 2-3 alkylene bridges; R 6-7 are individually selected from the group consisting of alkyl, fluoroalkyl, cycloaliphatic, aryl, and heterocyclic containing a oxygen, or nitrogen atom; and X is either an oxygen, or nitrogen substituted with a hydrogen, an alkyl or an aryl group.
