| 中文摘要 | Four novel coordination polymers, {[Zn(gauche-bime)(bdc)]center dot 0.5H(2)O}(n) (1), {[Zn(anti-bime)(HO-bdc)]center dot 2.5H(2)O}(n) (2), [Cu(gauche-bime)(0.5)(anti-bime)(0.5)(O2N-bdc)](n) (4) and [Ni-2(gauche-bime)(anti-bime)(O2N-bdc)(2)(H2O)(2)](n) (5) were successfully prepared by the solvothermal reactions of 1,2-bis(imidazol-1'-yl)ethane (bime), m-isophthalic acid (H(2)bdc) or its two derivatives (HO-H(2)bdc = 5-hydroxyisophthalic acid, O2N-H(2)bdc = 5-nitroisophthalic acid) with different metal ions. Interestingly, bime in the four complexes exhibit different conformations owing to the synergetic influence of coexistent neutral (-H), electron-donating (-OH) or electron-withdrawing (-NO2,) groups of the dicarboxylate ligands and different metal ions. In 1 and 2, only one conformation of bime (gauche in I and anti in 2) is displayed, while the mixed conformations of bime (gauche:anti = 1: 1) are observed in 4 and 5. At the same time, one previously reported compound {[Zn(anti-bime)(O2N-bdc)]center dot H2O}(n) (3) as a comparable substance in the research system was also mentioned, in which the anti-conformation of bime was observed.
