Abstract:
1. A method of synthesizing a heteroleptic cyclopentadienyl transition metal precursor, comprising performing at least one reaction to form a metal containing precursor, wherein the metal containing precursor comprises a precursor of the general formula: wherein: M is at least one member selected from the group consisting of: Mn; Fe; Ni; Co; Cu; Pd; Pt; Ag; Au; Ru; Os; Rh; Ir; and Re; (R (R R R L is a neutral ligand; 1≦m≦4 1≦n≦4; and 0≦k≦5, wherein the precursor is formed according to the synthesis reaction: wherein: X is independently selected from Cl; Br; and I; N is independently selected from Li; Na; and K; L and Q are neutral ligands; 0≦j≦5; and 0≦p≦5.
