摘要
By tuning the ratio of solvents in a binary solvent mixture, the coordination geometries of the metal centers were controlled and three 2Dcoordination polymers, [Zn(bdc)(dma)](n)1, [Zn(3)(bdc)(3)(dma)(2)](n)2 and {[Zn(bdc)(H(2)O)]center dot(DMA)}(n)3, were synthesized from zinc(II) nitrate and H(2)bdc in water/DMA solvents (H(2)bdc benzene-1,4-dicarboxylic acid, DMA N, N-dimethylacetamide). As the ratio of water/DMA increases, the number of DMA ancillary ligands coordinated to the zinc ion decreases, until all the DMA are substituted by water. The change in the ratio of solvents ( which also act as ancillary ligands) affords a means to adjust the local coordination environment of the zinc ion, leading to three types of SBUs, which further determine the topologies and the packing modes of the coordination polymers.
