Compositions including first and second silicon-containing compounds are described. The first silicon-containing compound includes a polyvalent transition metal having bonded thereto a hydrocarbyloxy group(s) and/or a (di-hydrocarbyl)(perfluoro/fluorinated-hydrocarbyl)silyloxy group(s), which is represented by Formula (I). The second silicon-containing compound includes a reaction product of a first reactant represented by Formula (II-A), which includes hyrdrocarbylsilyloxy groups, and a second reactant represented by Formula (II-B), which includes a perfluorohydrocarbyloxy group(s). The present invention also relates to, articles that include one or more layers formed from such compositions, methods of treating articles by applying thereover such compositions, and the second silicon-containing compound.
