Triazole based cadmium(II) anionic framework with 2-dimensional helical channels: Ionic liquid induced synthesis

A novel 2D MOF material [Cd2(AmTRZ)2·I3]·(R4N+)] (1; AmTRZ = 3-amino-1,2,4-triazole, R4N+ = tetraethylammonium), with an anionic skeleton has been hydrothermally synthesized in presence of an ionic liquid, tetraethylammonium hydroxide. 1 is endowed with large helical porous channels and two cadmium metal centers with different coordination environment around them besides showing presence of an unprecedentedly ordered extra-framework layer pattern of the encapsulated Et4N+ counter cations.
