The first [Re6(μ3-Se)8]2+ core-containing cluster carbonyls, [Re6-(μ3-Se) 8(PEt3)5(CO)][SbF6]2 and trans-[Re6(μ3-Se)8(PEt3) 4(CO)2]-[SbF6]2, were produced by reacting [Re6(μ3-Se)8(PEt3) 5l]I and trans-[Re6(μ3-Se) 8(PEt3)4I2], respectively, with AgSbF6 in CO-saturated dichloromethane solutions. Spectroscopic and crystallographic studies suggest significant cluster-to-CO back-donation in these novel cluster derivatives and interesting electronic structures. Thermal and photolytic studies of the mono-carbonyl complex revealed its interesting and synthetically useful reactivity in producing new cluster derivatives.
