In(C 6 F 5 ) 3 · CH 3 CN and In(C 6 F 5 ) 3 · glyme were synthesized from InCl 3 and Cd(C 6 F 5 ) 2 in CH 3 CN or glyme in 43% and 35% yield, respectively. Replacement of CH 3 CN or (C 2 H 5 ) 2 O by DMAP yielded the corresponding 1 : 1‐adduct. [PNP][In(C 6 F 5 ) 4 ] was best prepared from the corresponding cesium salt which was best synthesized from the reaction of stoichiometric amounts of In(C 6 F 5 ) 3 · CH 3 CN, (CH 3 ) 3 SiC 6 F 5 and CsF in good yield. [PNP][In(C 6 F 5 ) 4 ] crystallizes in the triclinic space group P 1, a = 1104.9(4) pm, b = 1442.4(6) pm, c = 1833.8(8) pm, α = 110.87(2)°, β = 92.04(3)°, γ = 96.55(3)°, Z = 2.
