The methods of preparation of ReO3F are revised. ReO3F is an amorphous yellow solid that crystallizes into colorless needles after prolonged heating. Its structure is that of a fluorine and oxygen bridged chain with hexa coordinated rhenium atoms (a = 670.9(2), b = 596.6(2), c = 1030.6(4) pm, β = 90.057(7)°, space group P2/c. In presence of donor solvents ReO3F·2L (L = (C2H5)2O, (CH3)2O, THF) are formed. ReO2F3, if crystallized from HF, exists in two crystalline forms, both are fluorine bridged chain polymers. (ReO2F3-I: a = 1539.7(3), b = 999.6(3), c = 924.4(2) pm, β = 95.25(1)°, space group P21/c; ReO2F3-II: a = 544.9(1), b = 494.2(1), c = 1253.7(2) pm, β = 98.543(7)°, space group P21/c. ReO2F3 crystallizes from CFCl3 or SO2FCl as fluorine bridged cyclic trimer (a = 881.4(4), c = 822.1(6) pm, γ = 120°, space group P63/m, or fluorine bridged cyclic tetramer (a = 1107.8(2), b = 999.4(2), c = 1347.9(3) pm, space group Cmca).

三氟化铼 ReO3F 的制备和结构，以及二氧化三氟化铼 ReO2F3 的多晶型

修订了 ReO3F 的制备方法。ReO3F 是一种无定形的黄色固体，长时间加热后结晶成无色针状。其结构为氟和氧桥连链，六配位铼原子（a = 670.9 (2), b = 596.6 (2), c = 1030.6 (4) pm, β = 90.057 (7) °, 空间群 P2) / c. 在供体溶剂存在下会形成 ReO3F2L (L = (C2H5) 2O, (CH3) 2O, THF)。ReO2F3，如果从 HF 中结晶出来，则以两种结晶形式存在，都是氟桥链聚合物。（ ReO2F3- I：a=1539.7(3)，b=999.6(3)，c=924.4(2)pm，β=95.25(1)°，空间群P21/c；ReO2F3-II：a=544.9(1)，b = 494.2 (1), c = 1253.7 (2) pm, β = 98.543 (7) °, 空间群 P21 / c. ReO2F3 从 CFCl3 或 SO2FCl 结晶为氟桥连环状三聚体 (a = 881.4 (4), c1 = 822. (6) pm, γ = 120°, 空间群 P63/m,
