Synthesis and molecular structure of the tetranuclear mu(4)-oxo-centered chromium complex [Cr-4(CH2CH2CH2NMe2)(4)(mu(4)-O)(mu-Cl)(6)]

The complex [CrCl3(THF)3] reacts with Li(CH2CH2CH2NMe2) in THF at room temperature (r.t.) to form the tetranuclear complex [Cr4(CH2CH2CH2NMe2)4(?4-O)(?-Cl)6] (1) where each chromium atom has a distorted octahedral coordination geometry with an oxygen atom shared among the four metal ions.
