The infrared spectra of [CpFe(CO) 2 ] 2 , [CpMo(CO) 3 ] 2 and Mn 2 (CO) 10 (Cp=η‐C 5 H 5 ) embedded in films of polystyrene (PS), poly(methyl methacrylate) (PMMA), and polystyrene‐polyacrylonitrile (PSAN), are comparable with those of the dimers in toluene, ethyl acetate and acetonitrile, respectively. Irradiation of the embedded dimers with UV light led to decomposition in PS and PMMA, while in PSAN the complexes Cp 2 Fe 2 (CO) 3 PSAN and Mn 2 (CO) 9 PSAN were formed, wherein a pendant nitrile group is coordinated to one of the metal atoms. Exposure of the embedded dimers to iodine vapour gave CpFe(CO) 2 I, CpMo(CO) 3 I and Mn(CO) 5 I with the reaction being much slower in PMMA than in PS.
