The compounds [As(CF3)2O(OH)]2(1) and As4(CF3)6O6(OH)2(3) have been prepared by oxidative hydrolysis of As(CF3)3, and a mixture of As(CF3)l2 and As(CF3)2l, respectively; [As(CF3)O(OH)Cl]2(2) was isolated from the reaction of compound (3) with SiMe3Cl. Crystals of compound (1) are triclinic, space group P, a= 584.2(1), b= 703.7(1), c= 958.6(1) pm, α= 103.91(1), β= 103.10(1), γ= 107.90(1)°, and Z= 1
