Acetylene storage performance of [Ni(4,4′-bipyridine)2(NCS)2]n, a switching square lattice coordination network

We report that the previously reported square lattice coordination network [Ni(4,4 '-bipyridine)(2)(NCS)(2)](n), sql-1-Ni-NCS, undergoes acetylene induced switching between closed (nonporous) and open (porous) phases. The resulting stepped sorption isotherms exhibit temperature controlled steps, consistent high uptake and benchmark working capacity (185 cm(-3) g(-1) or 189 cm(-3), 1-3.2 bar, 288 K) for acetylene storage.

Automated summary

The study demonstrates that a previously reported square lattice coordination network can undergo acetylene-induced switching between closed and open phases. The resulting stepped sorption isotherms exhibit consistent high uptake and benchmark working capacity for acetylene storage under temperature control.
