|Abstract:||Halide ion binding to the OH group of CpMn(CO)2(3- hydroxypyridine) complex has been investigated using infrared absorption spectroscopy via the νCO bands. Fluoride ion interaction in chloroform causes the largest redshift of up to 12 cm-1. The infrared bands of CpMn(CO)2L complexes containing N-H groups are redshifted to a similar extent. The displacement of the 3-hydroxypyridine ligand from the manganese complex by PPh3 is prevented because of a Mn-N bond strengthening effect induced by OH⋯F- binding. Density functional calculations also lend support to the large effect that OH⋯F- interaction has on the magnitude of the νCO redshift and Mn-N bond energy of CpMn(CO)2(3- hydroxypyridine). © 2013 Elsevier B.V.
