The oxidation of [(Cp’’’Co)2(μ,η2 : η2-E2)2] (E=As (1), P (2); Cp’’’=1,2,4-tri(tert-butyl)cyclopentadienyl) with halogens or halogen sources (I2, PBr5, PCl5) was investigated. For the arsenic derivative, the ionic compounds [(Cp’’’Co)2(μ,η4 : η4−As4X)][Y] (X=I, Y=[As6I8]0.5 (3 a), Y=[Co2Cl6-nIn]0.5 (n=0, 2, 4; 3 b); X=Br, Y=[Co2Br6]0.5 (4); X=Cl, Y=[Co2Cl6]0.5 (5)) were isolated. The oxidation of ...
