摘要

Solvothermal reactions of 3,5-bis(4-pyridyl)-pyridine (BPYPY) with 1,4-benzenedicarboxylate (1,4-bdc) and trans-1,4-cyclohexanedicarboxylic acid (trans-chdc) in the presence of Co(II) and Ni(II) salts in DMF/H2O or DMA/CH3CN/H2O produced three new compounds, namely, {[Co-3(BPYPY)(2)(1,4-bdc)(3)(H2O)(6)]}(n) (1), {[Ni-3(BPYPY)(2)(1,4-bdc)(3)(H2O)(6)]}(n) (2), {[Co(BPYPY)(trans-chdc)(0.5)(NO3)]center dot(H2O)}(n) (3). These compounds were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Compounds 1 and 2 are isomorphous and present 3,4-connected 3-fold interpenetrating tfz network with a point symbol of {6(3)}(2){6(4).8.10}(3). Compound 3 exists binuclear Co clusters which are linked by BPYPY and trans-chdc to generate a 4-connected cds network with the point symbol of {6(5).8} and displays antiferromagnetic characteristics. In addition, the thermal stabilities of these new compounds have also been discussed in detail.
