Abstract

Three Mn(III) quadridentate Schiff base compounds with N,N′-(1, 1, 2, 2-tetramethylethylene)bis(5-chlorosalicylideneiminato) (5-Clsaltmen 2-) were prepared and characterized: [Mn2(5-Clsaltmen) 2(H2O)2](ClO4)2 (1), [Mn2(5-Clsaltmen)2(5-Clsal)2](ClO 4)2 (2; 5-Clsal = 5-chlorosalicylaldehydonato), and [NEt4]2[Mn2(5-Clsaltmen)2(MeOH) 2][Fe(CN)6]ClO4·2MeOH (3). All compounds contain Mn(III) out-of-plane dimer units. The magnetic measurements revealed intra-dimer ferromagnetic exchange interaction between Mn(III) ions via phenolate oxygen, producing a S = 4 spin ground state.
