The synthesis and spectral characterization of isocyanide derivatives of MnCo(CO)9 of the type MnCo(CO)9-n(CNR)n (n=1,2; R=(p-MeOC6H4)NC, (2,6-xylyl)NC, (t-butyl)NC, (n-butyl)NC, (2,6-diisopropylphenyl)NC) are reported. The X-ray structure of MnCo(CO)8((2,6-xylyl)NC) (1) and MnCo(CO)7((2,6-xylyl)NC)2 (2) are reported herein as well. The structures of 1 and 2 contain a single metal-metal bond and no bridging ligands. The length of the Mn-Co bond is 2.870(1) and 2.9035(7) A in 1 and 2, respectively. The IR spectra of Mn(CO)5Br, Mn2(CO)10, MnCo(CO)9 and MnCo(CO)9-n(CNR)n (n=1,2; R=CH3) were calculated using density functional theory. The calculated IR spectra were employed to assign the structure of the MnCo(CO)9-n(CNR)n (n=1,2) compounds.
