Reductive aggregation of an organorhenium oxide: an unusual metal chain structure
Abstract
Electrochemical reduction of the dinuclear d1–d1 organorhenium oxide Me4Re2O41 or chemical reduction by cobaltocene cleanly yields the radical anion 1˙– which, upon controlled exposure to oxygen, disproportionates into hydrocarbons and the novel trinuclear complex [(C5H5)2Co][(Me)6Re3O6]2; this compound represents the first example of an acyclic organometallic oxide framework with metal–metal bonding.
