摘　　要：Constructed from 2,5-bis(4-pyridyl) thiazolo[5,4-d]thiazole(Py_(2) TTz),sulfate anions and metal ions Cd(Ⅱ),a new 3D luminescent metal-organic framework(LMOF) with good water stability is synthesized under solvothermal condition.[Cd(Py_(2) TTz)(SO_(4))]_a(Py_(2) TTz=2,5-bis(4-pyridyl) thiazolo[5,4-d]thiazole).It crystallizes in tetragonal space group P42_1 m_with a=6.830(3),b=6.830(3),c=17.676(12) A,V=824.5(8) A^(3),Z=4,M_(r)=504.83,D_(c)=2.033 g·cm^(-3),F(000)=496,GOOF=1.088,the final R=0.0434 and wR=0.0948 for 6301 reflections with I>2σ(Ⅰ).Upon excitation at 370 nm,the emission peak of the compound appears at 455 nm,which has a slight redshift compared to the free ligand Py_(2) TTz.The compound has potential to be a luminescence sensing material.
