Abstract:
1. A metal complex corresponding to the formula, CpM(X) x (L) t (X′) x′ (I), where Cp is a 1,2-azaborolyl anionic ligand, corresponding to the formula: wherein, R R M is a metal selected from Groups 3–10 or the Lanthanide series of the Periodic Table of the Elements; Z′Y is a divalent moiety with Z′ bonded to Cp and Y covalently or coordinate covalently bonded to M, wherein, Z′ is SiR Y is —O—, —S—, —NR R R L″ is a monodentate or polydentate Lewis base optionally bonded to R X is hydrogen or a monovalent anionic ligand group having up to 60 atoms not counting hydrogen; L independently each occurrence is a neutral ligating compound having up to 20 atoms, other than hydrogen, and optionally L and X are bonded together; X′ is a divalent anionic ligand group having up to 60 atoms other than hydrogen; x is 0, 1, 2, or 3; t is a number from 0 to 2, and x′ is 0 or 1.
