Summary of main observation and conclusion The coordination of silver cation to diphosphene Mes*P=PMes* ( 1 , Mes* = t Bu 3 C 6 H 2 ) was investigated in detail. The reaction of 1 with Ag[Al(OR F ) 4 ] (OR F = OC(CF 3 ) 3 ) in the ratios of 2 : 1, 3 : 2 and 1 : 2 led to the formation of the first cationic silver linked diphosphene complexes 2 — 4 . Complexes 2 and 3 contain two and three diphosphene molecules linked by the linear Ag(I) cation, respectively, and they feature unusual zig‐zag topologies. Complex 4 is a dinuclear silver complex, and each Ag(I) center features a tetrahedral geometry, coordinated by one phosphorus atom of diphosphene 1 and three chloro atoms of two CH 2 Cl 2 molecules.
