Abstract

LiRhF 6, LiIrF 6, Li 2RhF 6, and K 2IrF 6 were obtained again, but for the first time investigated by single crystal X-ray methods. Rubyred LiRhF 6 and yellow LiIrF 6 crystallize isostructural in the trigonal space group R3̄ - C 3i 2 (Nr. 148) with the lattice parameters LiRhF 6: a = 502.018(7) pm, c = 1355.88(3) pm, Z = 3 and d(Rh-F) = 185.5(1) pm; LiIrF 6: a = 506.148(4) pm, c = 1362.60(2) pm, Z = 3, d(Ir-F) = 187.5(3) pm (LiSbF 6-Typ). Yellow Li 2RhF 6 crystallizes tetragonal in the space group P4 2/mnm - D 4h 14 (Nr. 136) with a = 463.880(8) pm, c = 905.57(2) pm, Z = 2 and d(Rh-F) = 190.3(4)-191.4(3) pm (Trirutil-Typ). Yellow K 2IrF 6 crystallizes trigonal in the space group P3̄m1 - D 3d 3 (Nr. 164) with a = 578.88(7) pm, c = 465.06(5) pm, Z = 1 and d(Ir-F) = 194.0(6) pm, isotypic with K 2GeF 6.
