THE REACTION OF SCANDIUM TRIFLUORIDE WITH CYCLOPENTADIENYL SALTS AND THE CRYSTAL AND MOLECULAR STRUCTURE OF THE TRIMER OF FLUORODICYCLOPENTADIENYLSCANDIUM

The reaction of ScF3 with (C5H5)2Mg gives a mixture of (C5H5)3Sc and (η-C5H5)2ScF, not pure (C5H5)3Sc as reported previously.The same mixture is obtained on treating ScF3 with C5H5Na in tetrahydrofuran.The two products can be separated since (η-C5H5)2ScF is soluble in toluene whereas (C5H5)3Sc is not .The structure of (η-C5H5)2ScF shows it to be trimeric with a planar (Sc-F)3 ring (average Sc-F distance 2.046(8) Angstroem, F-Sc-F and Sc-F-Sc angles 86.5(3) and 153.4(4) degree, respectively).Crystal data: monoclinic, Cc, a 17.019(8), b 15.273(7), c 10.359(8) Angstroem, β 92.33(5) degree, Z = 4; Mo-Kα radiation, R = 0.076 for 1238 observed reflection and 325 variables.
