A new bimetallic Fe II –Cu II complex was synthesized and applied as a multifunctional device that is able simultaneously to detect cyanide in real water samples, amplify the colorimetric signal upon detection for naked‐eye recognition at the ppb level, and to convert the toxic cyanide into a much safer compound, cyanate, in situ. The mechanisms followed the so‐called indicator/catalyst displacement assay (ICDA) approach, in which one metal center acting as both a receptor/inhibitor is bridged to another metal center responsible for both signal transduction and catalysis.
