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, beta = 90.057(7)degrees, space group P2/c. In presence of donor solvents ReO(3)F(.)2L (L = (C2H5)(2)O, (CH3)(2)O, 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, beta = 95.25(1)degrees, space group P2(1)/c; ReO2F3-II: a = 544.9(1), b = 494.2(1), c = 1253.7(2) pm, beta = 98.543(7)degrees, space group P2(1)/c. ReO2F3 crystallizes from CFCl3 Or SO2FCl as fluorine bridged cyclic trimer (a = 881.4(4), c = 822.1(6) pm, gamma = 120 degrees, space group P6(3)/m, or fluorine bridged cyclic tetramer (a = 1107.8(2), b 999.4(2), c = 1347.9(3) pm, space group Cmca).
