The following salts have been synthesized and structurally characterized: Na[IrF]·2HO (2/, = 6.6327(4), = 10.0740(6), = 5.9283(5) Å, β = 122.3880(10)°) and Na[IrF]·2HO (-3, = 7.5963(3), = 7.5963(3), = 9.8056(4) Å) (for the first time) by single-crystal X-ray diffraction; the unit cell parameters of a tetragonal phase ( /, = 5.005(2), = 10.074(4) Å) of the stable α-Na[IrF] were determined for the first time; and the unit cell parameters of β-Na[IrF] (321, = 9.332(4), = 5.136(2) Å) and Na[IrF] (2/, = 5.567(4), = 5.778(4), = 8.017(2) Å, β = 90.41(2)°) were determined using powder X-ray diffraction (PXRD). The data of the thermal stability was obtained by differential thermal analysis (DTA) for all substances. The presence of Na[IrF]·HO monohydrate is predicted. H[IrF] was prepared in a solution and was demonstrated to behave as a strong dibasic acid.
通过单晶X射线衍射首次得到Na[IrF]·2H₂O（单斜晶系，a = 6.6327(4)，b = 10.0740(6)，c = 5.9283(5) Å，β = 122.3880(10)°）和Na[IrF]·2H₂O（立方晶系，a = 7.5963(3)，b = 7.5963(3)，c = 9.8056(4) Å）；首次测定了稳定的α-Na[IrF]四方相（P4/nmm，a = 5.005(2)，c = 10.0,74(4) Å）的晶胞参数；使用粉末X射线衍射（PXRD）测定了β-Na[IrF]（P321，a = 9.332(4)，c = 5.136(2) Å）和Na[IrF]（单斜晶系，a = 5.567(4)，b = 5.778(4)，c = 8.017(2) Å，β = 90.41(2)°）的晶胞参数。通过差示热分析（DTA）获得了所有物质的热稳定性数据。预测存在Na[IrF]·H₂O一水合物。在溶液中制备了H[IrF]，并证明其表现为一种强二元酸。
