    Abstract: Organometallic precursors and methods of depositing high purity metal films are discussed. Some embodiments utilize a method comprising exposing a substrate surface to an organometallic precursor comprising one or more of molybdenum (Mo), tungsten (W), osmium (Os), technetium (Tc), manganese (Mn), rhenium (Re) or ruthenium (Ru), and an iodine-containing reactant comprising a species having a formula RIx, where R is one or more of a C1-C10 alkyl, C3-C10 cycloalkyl, C2-C10 alkenyl, or C2-C10 alkynyl group, I is an iodine group and x is in a range of 1 to 4 to form a carbon-less iodine-containing metal film. Some embodiments advantageously provide methods of forming metal films having low carbon content (e.g., having greater than or equal to 95% metal species on an atomic basis), without using an oxidizing agent or a reductant.
