The AgI atom in the title hydrated solvated salt, [Ag(C18H15As)4](CF3CO2)·0.5CH3OH·0.5H2O, is coordinated by four As atoms from triphenylarsane ligands in a distorted tetrahedral geometry. In the crystal, O—H...O hydrogen bonding occurs between carboxylate groups of anions and lattice solvent molecules. Of the four triphenylarsane ligands in the Ag complex cation, two each have an equally disordered phenyl ring while the trifluoroacetate anion is disordered over two positions with respect to the lattice methanol and water molecules which both show half-occupyncy. The crystal studied was a non-merohedral twin with a 13.6 (1)% contribution of the minor twin component.
