In the title compound, [Ag{P(C6H11)2(C6H5)}2]ClO4·CH2Cl2, the AgI atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag—P = 2.3993 (4) and 2.4011 (4) Å; P—Ag—P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯Operchlorate inter­action of 2.873 (2) Å, which contributes to the slightly non-linear bond angle about the AgI atom. Weak inter­molecular C—H⋯O hydrogen-bonding inter­actions involving phenyl, cyclo­hexyl and dichloro­methane H-atom donors and perchlorate O-atom acceptors contribute to the stabilization of the crystal structure.
