 Abstract: Metal atom synthesis gives access to the bis(arene)chromium sandwich of 1,4 di-tert-butyl-benzene (5). 5 displays an axial sandwich structure with a linear arene–chromium–arene axis and a Cr–arene distance of 1.64 Å. Reduction of [{(η5-1,2,4 tri-tert-butyl-Cp)CoCl}2] with the trianion of decacyclene in THF produces the cobaltocene sandwich [(η5-1,2,4 tri-tert-butyl Cp)
2Co] 2 as black crystals in 65% yield. Electrochemistry shows that the monocations 2+ and 5+ are able to support reversibly the one-electron reduction to their corresponding neutral congeners.
