英文摘要	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.
