摘要：

On reaction with Ni(OAc)(2) and NaX the asymmetric compartmental ligand HL2 forms a heteropentanuclear nickel(II)-sodium(I) complex in which the core is assembled from two dinuclear [Ni2L2] units which are each linked to a Na atom by bridging mu(3)-acetato-groups. If KX or NH4X is used then a homotrinuclear nickel(II) complex is isolated. The crystal structures of [NaNi4(L-2)(2)(OAc)(6)(McOH)(2)][ClO4], 1, and [Ni-3(L-2)(2)(OAc)(2)(MeOH)(H2O)][BF4](2), 3, are reported [HL2 is the proligand 2-propyliminomethyl-4-methyl-6- {[methyl-bis(2-pyridin-2-yl-ethyl)-amino]-methyl}-phenol].
