Abstract

Abstract A nonanuclear nickel(II) cluster, [Ni9(H4L)2(OMe)6(OAc)10(H2O)4]·14H2O (1·14H2O), was synthesized by the reaction of an amide ligand H5L (= 2-hydroxy-4,6-dimethyl-N1,N3-bis(2-hydroxyethyl)-1,3-benzenedicarboxamide) with nickel acetate in the presence of triethylamine. The cluster molecule consists of two cubane units and a mononuclear central moiety, connected by acetate bridges. In the cubane cores, ferromagnetic interactions between nickel ions were operative, and the total spin ground state was S = 7 due to ferrimagnetic interactions between the two ferromagnetic cubane cores and the mononuclear nickel spacer.
