Chiral porous CN-bridged coordination polymer mimicking MOF-74 and showing magnetization photoswitching

Structural and electronic properties of MOF-74

A cyano-bridged tubular coordination polymer with dominant ferromagnetic interactions.

It is a challenge to synthesize a porous tubular coordination polymer with magnetic properties. Utilizing [Fe(II)(bipy)(CN)4](2-) (bipy = 2,2'-bipyridine) as the building block to react with Mn(2+), we successfully synthesized a cyano-bridged tubular coordination polymer with dominant ferromagnetic interactions. The inner surface of the heterometallic tube is hydrophilic, whereas the outer surf...

Quantum Sieving of H2 and D2 in Fe-MOF-74

An octacobalt cluster based, (3,12)-connected, magnetic, porous coordination polymer.

Solvothermal reaction of CoSO(4) with 2,6-di-p-carboxyphenyl-4,4'-bipyridine affords a novel, octacobalt cluster based, (3,12)-connected porous framework, which exhibits gas sorption and spin-glassy magnetic behaviour.

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

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.
