Benzotriazolate-mediated assembly of the discrete asymmetric pentanuclear nickel complex [Ni5(OH)(bta)5(acac)4(H2O)4](Hbta = benzotriazole, Hacac = pentane-2,4-dione)

Abstract

Reaction of [Ni(acac)₂(H₂O)₂] with benzotriazole (Hbta) in acetone–n-hexane yields the pentanuclear nickel complex [Ni₅(OH)(bta)₅(acac)₄(H₂O)₄]1; the novel structure of this compound is described, together with the results of magnetic susceptibility studies which indicate antiferromagnetic coupling between the nickel(II) ions within the complex.
