Solid state reconstructive phase transition from porous supramolecular network to porous coordination polymer

Abstract

Herein, we present an exceptional structural transformation from a porous supramolecular network to a porous coordination polymer. The transformation involves a change of interpenetrating dimensionality from 6-fold to 5-fold. Simultaneously, the spin state of nickel(II) is altered from S = 0 to S = 1, which is concomitant with the formation of the Ni–O_carboxylate coordination bonds.
