Adsorbate-dependent phase switching in the square lattice topology coordination network [Ni(4,4'-bipyridine) 2 (NCS) 2 ] n .

Switching coordination networks (CNs) featuring stepped sorption isotherms that are accompanied by phase changes offer promise for gas storage and separation applications. However, their responsiveness to different adsorbates remains largely understudied. Herein, we report the variable switching behaviour of a previously known square lattice (sql) topology CN, [Ni(4,4'-bipyridine) 2 (NCS) 2 ] (sql-1-Ni-NCS), with respect to nine gaseous adsorbates.
