摘要：

[Ni2(C5HF6O2)4(C2H6O)2(C4H8O2)], M(r) = 1125.9, triclinic, P1bar, a = 9.890 (4), b = 10.942 (4), c = 11.114(4) angstrom, alpha = 100.48(3), beta = 105.45(3), gamma = 108.87 (3)-degrees, V = 1048.5 (7) angstrom3, Z = 1, D(x) = 1.783 Mg m-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 1.057 mm-1, F(000) = 560, T = 298 K, R = 0.0747 and wR = 0.0638, for 298 variable parameters (S = 1.40) and 2759 reflections with F > 0sigma(F). A centrosymmetric complex containing a bridging molecule of dioxane is formed by two Ni(F6acac)2 complexes, each of which contains a molecule of ethanol coordinating axially [Ni(1)-O(5) = 2.032 (4) angstrom]. The Ni centers possess an octahedral coordination geometry and each forms bonds to two equatorial F6acac ligands. The bridging dioxane ligand is located on a crystallographic center of inversion, possesses a chair conformation, and forms bonds' to the two Ni atoms that measure 2.136 (4) angstrom.
