•Crystal structure of NO2SbF6 (150 K) differs from that of NO2AsF6 (291 K).•Crystal structure of XeF5SbF6 is isotypic to XeF5MF6 (M = Nb, Ru, Pt).•In XeF5Sb2F11 each [XeF5]+ cation has four interaction with three [Sb2F11]− anions.
NO2SbF6 crystalizes at 150 K in the orthorhombic Cmmm space group (No. 65) with a = 6.8119(7) Å, b = 7.3517(7) Å, c = 5.5665(5) Å, V = 278.77(5) Å3, and Z = 2. Its crystal structure exhibits a different packing of the [NO2]+ and [SbF6]− ions than in the known crystal structure of NO2AsF6. The XeF5SbF6 compound is orthorhombic at 150 K, space group Pnma (No. 62), with a = 16.7159(6) Å, b = 8.1093(3) Å, c = 5.7576(2) Å, V = 780.47(5) Å3, Z = 4, and it is isotypic with the known XeF5MF6 crystal structures of M = Nb, Ru, and Pt. The unit cell of XeF5Sb2F11 is triclinic at 200 K, P1¯ space group (No. 2), with a = 8.5223(8) Å, b = 8.5582(8) Å, c = 9.2012(8) Å, α = 68.799(8)°, β = 74.897(8)°, γ = 76.252(8)°, V = 596.35(10) Å3 and Z = 2. Each [XeF5]+ cation has four interactions with the three [Sb2F11]− anions.
