Abstract A newly synthesized bis‐pyridyl ligand having a diphenyl ether backbone ( LP6 ) displayed the ability to form crystalline coordination polymers ( CP1‐CP6 ) which were fully characterized by single crystal X‐ray diffraction. Most of the resulting polymers were lattice‐occluded crystalline solids—a structural characteristic reminiscent to gels. The reactants of the coordination polymers produced metallogels in DMSO/water confirming the validity of the design principles with which the coordination polymers were synthesized. Some of the metallogels displayed material properties like in situ synthesis of Ag nanoparticles and stimuli‐responsive gel–sol transition including sensing hazardous gases like ammonia and hydrogen sulfide.
