17. 2] moieties were located and refined isotropically; however, in view of the relative uncertainty of the positions of hydrogen atoms as determined by X-ray diffraction, we prefer to restrict the discussion of the hydrogen-bonding interaction to the more reliable F•••F separation. Nevertheless, for reference, the derived metrical parameters of the bifluoride ligand are: d(H2-F1) = 1.27(11) Å, d(H2-F3) = 1.13(12) Å; 〈(F1-H2-F3) = 157(8)○
