英文摘要:
      A new lanthanide/bismuth heterometallics hybrid molecule [Nd(DMF)8·Bi2I9nn(1) (DMF= N,N′-dimethyl formamide) was synthesized with Nd(NO3)3·6H2O,Bi(NO3)3·5H2O and NaI as starting materials in the DMF solvent. Its structure was determined by means of X-ray single diffraction and was further characterized with XRD,IR,UV-Vis spectrum. The title compound crystallizes in monoclinic system,space group P2(1)/c with a =1.0116(2)nm ,b =2.2465(5)nm ,c=2.6728(7)nm ,β= 97.915(9)°,V=6.016(2)nm 3,C24H56Bi2I9N8NdO8Mr= 2289.07,Z=4,Dc=2.527g·cm-3F(000)= 4092,μ(Mo )= 11.343mm-1,the final R1 =0.0717,wR2=0.1243. The structure of [Nd(DMF)8·Bi2I9n(1) consists of complex cations [Nd(DMF)8+3 and polyanion (Bi2I9)-3,a 3-D heterometallics hybrid framework was constructed based on the versatile C—H…I hydrogen bonds in the crystal. Its adsorption spectrum suggests its semiconductor nature with band gap of 2.23eV,and its fluorescence were the contribution of organic and inorganic moieties,so conclusion could be drawn that the hybrid can reflect the functions of two moieties.
