An unusual (3,4,5)-connected 3D cadmium metal-organic framework as a luminescent sensor for detection of Cr2O72− in water

An unusual 3D (3,4,5)-connect framework {[Cd2(L)(FA)(H2O)3]·H2O}n has been hydrothermal synthesized, which features an unprecedented topology with a point symbol of (42·62·72·84)(42·6)(64·82). The results of luminescence quenching show that 1 is a good luminescence sensor for detection of Cr2O72− anion in aqueous phase and the detection limit of Cr2O72− is 2.16 μM.173
