摘      要：Three coordination polymers, namely, {[Zn（cmba）（bpp）]×H2O}n（1）, {[Zn（cmba）（bpa）1.5]×2.25H2O}n（2） and {[Cd（cmba）（bpa）（H2O）]×H2O}n（3）（H2cmba = 3-（carboxymethyl）benzonic acid, bpp = 1,3-bis（4-pyridyl）propane and bpa = 1,2-bi（4-pyridyl）ethane）, were synthesized under solvothermal conditions and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis（TGA）, and single-crystal X-ray diffraction. Complex 1 features a 2D（4,4） grid layer with a side length of 9.827（10）/12.176（13） A. Complex 2 shows a 2D → 2D 2-fold interpenetrating layer structure through the flexible bpa coligands. Compound 3 presents a 2D layer formed from the metal-carboxylate chains further extending through bpa pairs. Furthermore, the solid state luminescent properties of complexes 1~3 were investigated at room temperature.
