Abstract

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