主　　题：cadmium polymer 4 4'-bipyridine m-nitrobenzoic acid crystal structure 

摘      要：A new cadmium polymer [Cd（NBA）（μ3-OH）（4,4＇-bipy）1/2]n 1 （NBA=m-nitrobenzoic acid and 4,4＇-bipy=4,4-bipyridine） has been synthesized by hydrothermal reaction. Its structure was determined by single-crystal X-ray diffraction method, and characterized by elemental analysis and IR spectrum. The crystal is of monoclinic, space group C2/c, with a=15.6912（9）, b=25.9394（15）, c=6.7332（4）A, β=114.7700（10）°, V=2488.4（3）A^3, C12H9CdN2O5, Mr=373.61, Z=8, Dc=1.995 g/cm^3,μ=1.776 mm^-1, F（000）=1464, R=0.0411 and wR=0.1128 for 2130 observed reflections （I 〉 2σ（I））.X-ray diffraction studies reveal that the compound features a layered structure, in which 4,4＇-bipy ligands bridge Z type of double chains [Cd（μ3-OH）]n and NBA ligands locate at the two sides of the layer. The π-π interactions between the benzene rings of NBA ligands of two adjacent layers lead to the 3D framework.
