| 英文摘要 | By means of the solvent effect, three new azido-copper 1D coordination polymers, [Cu(4-aba)(N-3)] (1), [Cu(4-aba)(N-3)(CH3OH)] (2), and [Cu(4-aba)(N-3)(C2H5OH)] (3) (4-aba = 4-azidobenzoic acid), were successfully prepared in the presence of Cu2+ ion, NaN3 and 4-azidobenzoic acid. Interestingly, 1 can be employed as a precursor and transformed to 2 and 3via the coordination of methanol or ethanol, respectively. Meanwhile, the identical products of 1, namely 1a and 1b, could be obtained from both 2 and 3 by a dealcoholized process. As a result, the geometric configurations of Cu(ii) ions vary from the tetracoordinated square-planar in 1 to the hexacoordinated octahedron in 2 or 3. Compound 1 displays a well-isolated 1D chain with dual-bridges of EO-azido and syn,syn-carboxylate, while isomorphic 2 and 3 are triple-bridged chain-like motifs containing EO-azido, syn,syn-carboxylate and mu 2-alkanol. The structural transformations caused by the intervention of alkanol molecules modulate the intrachain Cu-Cu distances (3.570 for 1, 3.204 angstrom for 2 and 3.154 angstrom for 3) and Cu-N-Cu angles (127.3 degrees for 1, 106.82 degrees for 2 and 104.81 degrees for 3). This modulation, however, further leads to different intrachain ferromagnetic interactions (J = 28.4 cm(-1) for 1, 67.6 cm(-1) for 2, 40.2 cm(-1) for 3) that are qualitatively demonstrated by theoretical calculation. More importantly, the significant scenarios of magnetic ordering and slow magnetic relaxation, which are infrequent in most of the reported azido-copper cases, are only observed in 2 and 3, due to the distinct interchain networks among 1-3. In addition, heat-capacity measurements highlight the characteristics of long-range ferromagnetic ordering in 2 and 3. |
