to the tunability of linking ligands, these complexes show different interesting topological networks, namely uninodal umc three-dimensional network for 1, mtc three-dimensional non-manifold topology for 2, (4,4) net for the two-dimensional structure of 3, dmp-c interpenetrated network for 4, and one-dimensional ladder chain for 5. Notably, all complexes exhibit selectivity and sensitivity for Fe3+
