Claim:
A method of forming a layer on a substrate, the method comprising: contacting a precursor composition with a surface of a substrate, wherein the precursor composition comprises one or more complexes of the formula: L y RhY z , wherein: each L group is independently a neutral or anionic ligand; each Y group is independently a pi bonding ligand selected from the group of CO, NO, CN, CS, N 2 , PX 3 , PR 3 , P(OR) 3 , AsX 3 , AsR 3 , As(OR) 3 , SbX 3 , SbR 3 , Sb(OR) 3 , NH x R 3-x , CNR, and RCN, wherein R is an organic group, X is a halide, and x=0 to 3; with the proviso that L is not cyclopentadienyl when Y is CO; y=1 to 4; and z=1 to 4.
