英文摘要	Tetradentate schiff base ligands h2l (h(2)saltmen, h(2)salen, h-2-5-brsalen, and h-2-3,5-brsalen), derived from the condensation of the corresponding salicylaldehyde or its derivatives with 1,1,2,2-tetramethylethyldiamine or 1, 2-diaminoethane, reacted with mn-iii acetate or perchlorate salts and sodium azide or sodium cyanate to produce five mn-iii dimer complexes, [mn(saltmen)(o2cch3)](2)(.)2ch(3)co(2)h (1), [mn(saltmen)(n-3)](2) (2), [mn(salen)(nco)](2) (3), [mn(3,5-brsalen)(3,5-brsalicylaidehyde)](2) (4), and [mn(5-brsalen)(ch3oh)](2)(cio4)(2) (5). these new complexes have been characterized by ir, elemental analyses, crystal structural analyses, and magnetic studies. within these mn-iii dimeric complexes, two mn-iii ions are connected by phenolate oxygen atoms with acetate, azide, cyanate, a 3,5brsalicylaclehyde anion, and a neutral methanol molecule as the axial ligands for complexes 1-5, respectively. complexes 1-4 exhibit intradimer ferromagnetic exchange and display frequency dependence of ac magnetic susceptibility, possibly showing single-molecule-magnet (smm) behavior. in contrast, complex 5 shows an intradimer antiferromagnetic coupling probably originating from the relatively shorter mn-o* distance, compared to those of complexes 1-4.
