Organotin compositions suitable for radiation based patterning have ligands providing fluorinated groups and unsaturated carbon-carbon bonds, such as CC bonds. The fluorinated groups and unsaturated carbon-carbon bonds may or may not be located on the same ligand. Blends of precursors with different ligands provide added flexibility with respect to precursor design. Fluorinated organometallic compounds can be represented by the formula R.sup.UFSn(OR).sub.3, wherein R.sup.UF is an organo group with 1 to 31 carbon atoms with at least one CC bond and at least one fluorine atom bonded to a carbon, with the organo group forming a CSn bond, wherein R is an organo group with 1 to 10 carbon atoms. Precursors are suitable for solution based deposition or vapor based deposition.

A zirconium polymer composition comprising a zirconium polymer selected from the group consisting of polymeric zirconium oxychloride, polymeric zirconium acetate, and polymeric zirconium nitrate and having metal particles thereon is beneficial to aid in the removal of biological contaminants, such as bacteria, virus, yeast, algae, and amoeba, from fluids, including air and water. In this composition, the metal is selected from the group consisting of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), silicon (Si), boron (B), copper (Cu), gold (Au), lead (Pb), mercury (Hg), nickel (Ni), silver (Ag), thorium (Th), tin (Sn), zinc (Zn), and mixtures thereof, and the metal particles are about 0.001% by weight to about 30% by weight of the composition. These zirconium polymer compositions are used in methods for removing biological contaminants from fluids.
