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.
