A 3-D lanthanide-organic framework based on in situ formed benzene-1,2,3,4-tetracarboxylate ligand

One new 3-D open lanthanide-organic framework {[La2(L)1.5(H2O)4]∙2.75H2O}∞ (1) (L = benzene-1,2,3,4-tetracarboxylate) has been hydrothermally synthesized through in situ ligand formation, which exhibited an unusual (4,5,6)-connected (42.84) (32.44.52.62)4(32.45.53.64.7)2 topology.
