X-Ray diffraction study of a single crystal of (C₆H₅)₄AsRuCl₄(H₂O) ₂·H₂O showed that it is monoclinic with a = 15.059, b = 16.711, c = 10.996 A?, β = 99.88°, D_x = 1.619 g cm^-3. The space group is P2₁/n and there are four formula units per unit cell. The ruthenium is surrounded by an octahedron composed of the four chlorine atoms and two water molecules. A cis configuration was found for the waters in the octahedron. The average Ru-O and Ru-Cl distances are 2.12 and 2.34 A. An unsymmetrical configuration was found for the tetraphenylarsonium ion, with an average As-C bond length of 1.91 A.
