Two supramolecular coordination polymers, [HgI2(L1)·0.5H2O]∞ (1) and [HgI2(L2)·0.4CH3OH]∞ (2), have been prepared by ligands L1 (L1 = bis[4-(4- pyridylmethyleneamino)phenyl] ether) and L2 (L2 = N,N′-bis(3-pyridylmethyl)-diphthalic diimide) with HgI2, respectively. 1 formed an interestingly infinite cross-linked double helical structure, whereas 2 formed the one-dimensional zigzag chains, which are parallel with each other. 相似文献
