ABSTRACT:
This invention pertains to complex mixtures of the formula M is a metal having a valence of from 2–6, L1 is an anionic ligand and L2 is a siloxide or silyl amide ligand suited for producing stable thin-film metal silicates, v is equal to the valence of the metal, and 0<x<v. The bonding is such that an M—O—Si or an M—N—Si linkage exists, respectively, and the stability for the complex is provided by the organic ligand. The invention also relates to a process for preparing the metal siloxide complexes.Thus, the complexes can be represented by the formulasin-line-formulae description="In-line Formulae" end="lead"?(R)mM—(O—SiR1R2R3)nin-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?andin-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(R)mM—[N—(SiR1R2R3)y(R4)2- y]nin-line-formulae description="In-line Formulae" end="tail"?wherein M is a metal having a valence of 2–6, m and n are positive integers and m plus n is equal to the valence of the metal M. The R type groups, i.e., R, R1, R2, R3, and R4represent an organo ligand.
