1. A solution comprising a mixture of an organic solvent with a selected water content and a first monoalkyl tin trialkoxide (RSn(OR′)3), wherein the solution has a tin concentration from about 0.004 M to about 1.0 M and wherein the selected water content is at least about 250 ppm by weight and wherein the solution is stable for at least 42 days, wherein R and R′ are independently a hydrocarbyl ligand with one or more carbon atoms optionally substituted with one of more heteroatom functional groups, wherein the hydrocarbyl ligand comprises an alkyl, an aryl, an alkenyl, or a cycloalkyl group with 1-31 carbon atoms.
