Formation and solid state structure of a tetranuclear oxoaryloxide cluster of barium, [Ba4(µ4-O)(µ2-OC6H2(CH2NMe2)3-2,4,6)6]·3(toluene)

Abstract

The tetranuclear oxo–aryloxide cluster, [Ba₄(µ₄-O)(µ₂-OC₆H₂(CH₂NMe₂)₃-2,4,6)₆]·3(toluene), synthesized from the reaction of K[(OC₆H₂(CH₂NMe₂)₃-2,4,6] and BaI₂ in tetrahydrofuran, crystallizes from toluene as a tetrahedron of barium atoms encapsulating a single oxo ligand, the metal centres coordinated by six µ₂-aryloxide groups and the nitrogen atoms of the ortho-dimethylaminomethyl groups.
