| 英文摘要 | The work in this report describes the synthesis, characterization, crystal structure and magnetic properties of a two-dimensional azido-bridged (NiMnII)-Mn-II heterometallic coordination polymer, [{((NiLMnII)-L-II)(2)(mu(1,1,3)-N-3)(2)} (mu(1,3)-N-3)(2)](n) (1), in which the H2L Schiff base is the [2 + 1] condensation product of 3-methoxysalicylaldehyde and 1,3-diaminopropane. In 1, two bis(mu-phenoxo)-mu(1,1,3)-azido-(NiMnII)-Mn-II dinuclear units are inter-linked to form a dimer-of-dinuclear moiety {(NiMnII)-Mn-II}(2); the {(NiMnII)-Mn-II}(2) structural units are further interlinked with each other by mu(1,3)-azido ligands to form a layered coordination polymer. Upon cooling, the chi T-M product slowly decreases from 300 K to about 100 K, then increases abruptly from 3.74 cm(3) K mol(-1) at 100 K to 113.2 cm(3) K mol(-1) at 30 K, indicating a ferrimagnetic behaviour; a three-dimensional magnetic order below 37 K was determined by the divergence in the ZFC-FC measurements and ac measurements, in which the peak temperature 35 K in the in-phase at different frequencies suggests that the Curie temperature is 35 K, whereas the out-of-phase is somewhat frequency dependent, due to the glassy magnet behaviour. The title compound is among the rare examples of metallo-organic systems having a magnetic ordering Curie temperature above 30 K. Other interesting aspects in 1 regarding magnetic properties and structural features are discussed. |
