Tetra­kis(triphenyl­arsane-κAs)silver(I) trifluoro­acetate hemihydrate methanol hemisolvate

The Ag(I) atom in the title hydrated solvated salt, [Ag(C(18)H(15)As)(4)](CF(3)CO(2))·0.5CH(3)OH·0.5H(2)O, 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.
