A dimeric mn(III) complex of a quadridentate schiff base ligand. Synthesis, structure and ferromagnetic exchange

Abstract

The synthesis, crystal structure and magnetic properties of [Mn(III)L(H2O)l2(H2O)(ClO4) (1) (L = N,N'-bis(rac-5-chlorosalicylidenato)-l,2-diaminopropane) are reported. Compound 1 consists of a structurally dinuclear system in which two Mn ions are bridged by the oxygen atoms of μ-phenoxo ligands. Low temperature magnetic susceptibility measurements show a ferromagnetic intra-dimer interaction with J = +1.75 cm-1, g = 2.01 and α = -0.32. © 2008 Verlag der Zeitschrift für Naturforschung,.
