3D porous and 3D interpenetrating triple framework structures constructed by aurophilicity-coordination interplay in {Mn[Au(CN)2]2(H2O)2}n and {KFe[Au(CN)2]3}n

Two cyano-bridged heterobimetallic coordination polymers {Mn[Au(CN)2]2(H2O)2}n(1) and {KFeA[Au(CN)2]3}n(2), have been synthesized from [Au(CN)2]– building blocks and structurally Acharacterized. In both complexes aurophilicity play an important role in determining the A3D open microporous framework and the interpenetrating triple framework for 1 and 2, Arespectively. Both aqueous solutions of 1 and 2 display interesting luminescent properties
