摘要

With triazole-modified derivative as link,one new framework[Cd5(μ5-HL2-)2(μ4-L3-)2(H2O)10]·2H2O(1,H3L =2-(1,2,4-triazol-1-yl)benzene-l,3,5-tricarboxylic acid) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction,powder X-ray diffraction and elemental analysis.Complex 1 exhibits a 3D (3,4,6)-connected net cross-linked by binuclear[Cd2(COO)5]-cluster and mononuclear Cd(Ⅱ)geometry via HL2-/L3-ligands.It crystallizes in triclinic system,space group P(-1) with a =7.7411(11),b =9.8813(15),c =20.177(3) (A),a =85.547(4)°,β =80.603(4)°,γ =67.976(3)°,V=1411.3(4) (A)3,Z =1,Mr =1876.89 g/mol,Dc =2.208 mg/m3,μ =1.97 mm-1,F(000) =918,GOOF =1.03,the final R =0.0869 and wR =0.1950 for 3127 observed reflections with Ⅰ ＞ 2σ(Ⅰ).The solid photoluminescent behaviour of 1 has been further functionally investigated.
