Unusual effects of the bulky 1-norbornyl group in cobalt carbonyl chemistry: low-energy structures with agostic hydrogen atoms

Abstract

Low-energy (nor)Co(CO)n (n = 3, 2) and (nor)2Co2(CO)n (nor = 1-norbornyl; n = 6, 5) structures are found to have agostic hydrogen atoms from a CH2 group adjacent to the Co–C bond forming C–H–Co bridges. In addition, low-energy structures are found with (nor)CO acyl ligands resulting from carbonyl migration.
