    Abstract: An organotin precursor solution is described comprising an organic solvent, an optional additive, and an organotin composition represented by one or more organotin compounds represented by the formula RSnL3, wherein each R is independently a hydrocarbyl ligand having from 1 to 31 carbon atoms and each L is independently a hydrolysable ligand, wherein the total concentration of Sn is from about 0.001M to about 0.5 M/ The solvent can comprises a linear alcohol with from 1 to 6 carbon atoms, and the organotin precursor solution can have an initial water content from about 100 ppm to about 10,000 ppm, in which the organotin precursor solution has a reduced rate of water dissipation relative to an equivalent organotin precursor solution formed with 4-methyl-2-pentanol. The organo precursor solutions can be prepared through the selection of an appropriate stabilizing compound, which can be a linear, short chain alcohol and an appropriate additive.
