摘要:
Two coordination polymers, [Cd(L1)(bib)](n) (1) and [Cd(L2)(bib)(0.5)](n) (2) [H(2)L1 = 5-hydroxyisophthalic acid, H(2)L2 = 5-methylisophthalic acid and bib = 1,4-bis(2-methyl-imidazol-1-yl)butane], have been synthesized and characterized by IR, elemental analysis, and X-ray diffraction. Compound 1 shows a 2-D layer structure and 2 is a two-fold interpenetrated 3-D pcu topology. The results suggest that the 5-position group affects the structure of coordination polymers. Luminescence properties of 1 and 2 are investigated.
