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-paH) 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) ,V = 7189.9(8) 3,Z = 8,C34H32.16Cd2N6O12.08,Mr = 942.85,Dc = 1.742 g/cm3,μ = 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 -bidentate rigid dipyridyl ligand 4,4’-bipyridine (4,4’-bpy) by using a hydrothermal method, whose structure was determined by single-crystal X-ray diffraction and its luminescent property was also documented.

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.
