Darstellung und Struktur des Bis(triphenylarsoranyliden)ammoniumchlorids / Preparation and Structure of Bis(triphenvlarsoranylidene) Ammonium Chloride

The reaction of Ph 3 AsCl 2 (1) and N(SiMe 3 ) 3 (2) yields [Ph 3 As-N-AsPh 3 ] + Cl (3) as a crystal­line white solid, soluble in CH 3 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.
