摘要:
A new 3D lanthanide metal-organic framework, {[Ce(L)(DMF)]center dot 2.5(DMF)center dot 3(H2O)}(n) (1) (H3L = N,N',N"-tris (4-carboxyphenyI)-1,3,5-benzenetricarboxamide. DMF = N,N'-dimethylformamide) has been synthesized under solvothermal condition. Compound 1 features a 3D non-interpenetrated binodal (4, 8)-connected AIB(2) topology with a Schlafli symbol of (4(5).6)(2)(4(10).6(14).8(4)), where the C-3 symmetry ligand H3L evolves into an unusual 4-connected node and dinuclear cerium cluster acts as an 8-connected node. Furthermore, compound 1 displays blue emission in the solid state at room temperature. (C) 2011 Elsevier B.V. All rights reserved.
