摘要：

The synthesis, crystal structure and magnetic properties of dinuclear [Mn(III)(salen)(H2O)](2)(ClO4)(2) (1) and polynuclear [Mn(III)(salen)(NO3)](n) (2) (salen =N,N'-bis(salicylideneaminato)ethylene) are reported. Compound 1 consists of a structurally dinuclear system in which two Mn ions are bridged by the oxygen atom of mu-phenoxo of the salen ligands. Compound 2 is a linear polymeric chain in which the Mn ions are linked by NO3- groups. Cryomagnetic measurements show ferromagnetic interaction with J = 6.30 cm(-1) and D = - 1.70 cm(-1) for 1 and antiferromagnetic interaction with J = - 0.55 cm(-1) and D = - 0.43 cm(-1) for 2.
