<jats:p>The reaction of Ph<jats:sub>3</jats:sub>AsCl<jats:sub>2</jats:sub> (1) and N(SiMe<jats:sub>3</jats:sub>)<jats:sub>3</jats:sub> (2) yields [Ph<jats:sub>3</jats:sub>As-N-AsPh<jats:sub>3</jats:sub>]<jats:sup>+</jats:sup>Cl (3) as a crystalline white solid, soluble in CH<jats:sub>3</jats:sub>OH and acetone. 3 might be used to stabilize unusual anions. It crystallizes as a 1:1 toluene adduct in the space group C2/c with a - 1585.3(3). b = 1058.7(2). c = 2266.3(4) pm. β = 94.40(2)° and Z = 4. The cation in 3 lies on a crystallographic two-fold axis with As-N-As 123.9(1)°. As-N 174.9(3). and As-C 196.7(5). 197.6(5). 193.2(5) pm. </jats:p>
