Abstract

The synthesis and magnetic properties of three new members of a family of salicyaldoxime based [Mn-6] single-molecule magnets possessing new structural types, core topologies and Mn oxidation state distributions are reported. The isostructural complexes [(Mn6O2)-O-III(R-sao)(6)(X)(2)(EtOH)(6)] (R = Et, X = Br (1); R = Me, X = I (2)) exhibit single-molecule magnet behaviour with spin Hamiltonian parameters S = 12, g = 1.98 and D = -0.36 cm(-1) in both cases. The hexametallic cluster [(Mn4Mn2O2)-Mn-III-O-IV(OMe)(4)-(Et-sao)(6)(MeOH)(2)]center dot MeOH (3 center dot MeOH) possesses a planar rod-like topology and a mixed valent [(Mn4Mn2III)-Mn-IV] core, which is unprecedented in this family of [Mn-6] SMMs.
