In the title solvated salt, [Ag(C₁₈H₁₅P)₄](CF₃CO₂)·C₂H₅OH, the Ag^I atom is coordinated by four P atoms from triphenylphosphane ligands in a distorted tetrahedral geometry. The anion and solvent are engaged in weak O-HO hydrogen bonds. Of the four triphenylphosphane ligands, two each have an equally disordered phenyl ring while the Ag^I atom is disordered over two positions in a 0.9595 (15):0.0405 (15) ratio and the trifluoroacetate anion is equally disordered over two positions with respect to the lattice ethanol molecule.
