Coordination polymers based on trinuclear heterometallic pivalates and polypyridines: Synthesis, structure, sorption and magnetic properties

► Different polypyridines are examined as linkers for trinuclear pivalates. ► Replacement of 4,4′-bipyridine by dipyridylethylene in porous coordination polymer. ► “Expansion” of pores makes crystal lattice more flexible. ► Sorption capacity strongly depends on adsorbate type. ► Magnetic properties simulated considering zero-field splitting of cobalt(II).
