The infrared spectra of derivatives of manganese carbonyl of the type Mn(CO)5L (L = H, CH3, CD3, C6H5, C6H5CH2, Cl, Br, I) as well as of the parent carbonyl have been recorded in the 200–700 cm−1 region in cyclohexane and carbon tetrachloride solutions. In addition, the corresponding spectra of the ionic derivatives [Mn(CO)6]+-BF4- and Et4N-[V(CO)6]- have been recorded as Nujol mulls. Assignments for the metal-carbon stretching and metal-carbon-oxygen bending modes are discussed with special mention of possible correlations with the relevant carbon-oxygen stretching modes.
