topologies, respectively, 2 exhibits a rare (4,4)-connected 2-node 2D 4,4L62 network, 3 reveals an unprecedented 3D (3,3,4,5)-connected framework with the point symbol 4·92}242·82·92}42·84·93·10}293}2 and 4 presents an unusual (3,5)-connected 3D gra topological framework. The results show that the coordination mode of dicarboxylate ligands and the auxiliary N-containing linkers have a crucial impact
