Abstract
The invention relates to compounds of the general formula SnR.sup.1.sub.a R.sup.2.sub.b R.sup.3.sub.c, in which R.sup.1 is an alkyl group with 1 to 4 carbon atoms, R.sup.2 is an acetate group, R.sup.3 is a trifluoroacetate group, a has a value of 1 or 2, b has a value of 1 or 2 and c has a value of 1 or 2, with the proviso that the sum of a+b+c=4. The invention also relates to a method for the synthesis of these compounds and to a material for producing electrically conductive and infrared-reflective fluorine-doped tin oxide layers on glass, glass ceramic and/or enamel surfaces, the material containing tin compounds of the formula SnR.sup.1.sub.a R.sup.2.sub.b R.sup.3.sub.c or mixtures of these tin compounds, the mixture corresponding to the general formula SnR.sup.1.sub.x R.sup.2.sub.y R.sup.3.sub.z, wherein x has a numerical value of 1 to 2, y a numerical value of 0.1 to 2.9 and z a numerical value of 0.1 to 2.9, the sum of x+y+z being 4, dissolved in a polar organic solvent.
