| 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/cm3,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.
