Abstract: | Single Crystal Investigations on LiMF6 (M = Rh, Ir), Li2RhF6, and K2IrF6 LiRhF6, LiIrF6, Li2RhF6, and K2IrF6 were obtained again, but for the first time investigated by single crystal X‐ray methods. Rubyred LiRhF6 and yellow LiIrF6 crystallize isostructural in the trigonal space group R3 – C23i (Nr. 148) with the lattice parameters LiRhF6: a = 502.018(7) pm, c = 1355.88(3) pm, Z = 3 and d(Rh–F) = 185.5(1) pm; LiIrF6: a = 506.148(4) pm, c = 1362.60(2) pm, Z = 3, d(Ir–F) = 187.5(3) pm (LiSbF6‐Typ). Yellow Li2RhF6 crystallizes tetragonal in the space group P42/mnm – D144h (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 K2IrF6 crystallizes trigonal in the space group P3m1 – D33d (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 K2GeF6. |
