摘　　要：A novel cadmium（Ⅱ） coordination polymer [Cd2（3-pa）4（4,4＇-bpy）（H2O）].3.08H2O 1 has been synthesized by pyridine-3-carboxylate （3-pall） and CdO with exo-bidentate rigid dipyridyl ligand 4,4＇-bipyridine （4,4＇-bpy） by using a hydrothermal method, its structure was determined by single-crystal X-ray diffraction and its luminescent property was also documented. Complex 1 crystallizes in orthorhombic space group Pbcn with a = 21.4074（14）, b = 27.1119（18）, c = 12.3879（8） A, V = 7189.9（8） A3, Z = 8, C34H32.16Cd2N6O12.08, Mr= 942.85, Dc = 1.742 g/cms, p = 1.255 mm-1 and F（000） = 3766. The structure was solved by direct methods and refined to R = 0.0353 and wR = 0.0891 for 6278 observed reflections （I 〉 2σ（I））. The most prominent structural feature is the mutual interpenetration of two identical 3-D open frameworks via filling the large void space, which gives a 2-fold interpenetrating architecture during the self-assembly process.A novel cadmium（Ⅱ） coordination polymer [Cd2（3-pa）4（4,4＇-bpy）（H2O）].3.08H2O 1 has been synthesized by pyridine-3-carboxylate （3-pall） and CdO with exo-bidentate rigid dipyridyl ligand 4,4＇-bipyridine （4,4＇-bpy） by using a hydrothermal method, its structure was determined by single-crystal X-ray diffraction and its luminescent property was also documented.
