AbstractThe systematic exploration of the reactivity of [Mn(hfacac)] with R-salicyloximes (R-saloxH: R = H, Me, Et) yielded a family of clusters with nuclearities ranging from Mn to Mn. The compounds with formula [Mn(O)(salox)(CFCOO)(EtOH)] (1) and [Mn(salox)(O)(N)(HO)(MeOH)] (4) show two or four linked {Mn(μ-O)(salox)} triangular subunits. Magnetic measurements revealed spin ground states of S = 4 for 1 and S = 8 for 4, as well as single-molecule magnet responses and magnetic hysteresis above 2 K. The cubic [Mn(Mesalox)(MesaloxH)] (2), the hexanuclear [Mn(Etsalox)(O)(MeO)(MeOH)] (3) and the octanuclear [Mn(Mesalox)(O)(N)(MeOH)] (5) are polymorphs of previously reported systems. Small structural changes allows an S = 11 ground state for 3.
