Eg. Bakalbassis et al., BENZOTRIAZOLATE-MEDIATED ASSEMBLY OF THE DISCRETE ASYMMETRIC PENTANUCLEAR NICKEL-COMPLEX [NI-5(OH)(BTA)(5)(ACAC)(4)(H2O)(4)] (HBTA=BENZOTRIAZOLE, HACAC=PENTANE-2,4-DIONE), Journal of the Chemical Society, Chemical Communications, (13), 1995, pp. 1347-1348
Reaction of [Ni(acac)(2)(H2O)(2)] with benzotriazole (Hbta) in acetone
-n-hexane yields the pentanuclear nickel complex: [N i(5)(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 ind
icate antiferromagnetic coupling between the nickel (II) ions within t
he complex.
