Guest-induced crystal-to-crystal expansion and contraction of a 3-D porous coordination polymer

Abstract

A silver(I) 3-D porous coordination polymer (PCP, 1) with a sodalite topology undergoes a remarkable reversible crystal-to-crystal expansion and contraction upon exposure to different solvents. Notably, complete desolvation of 1 also facilitates a transformation to a non-porous 2-D coordination polymer (2).
