Abstract
The reaction of mercuric acetate with closo-1 ,2-Li2-1 ,2-C2BloHlo yielded (9)mercuracarborand-3, (C2BloHloHg), (l), in 60% yield. Compound 1 was characterized by multinuclear NMR spectroscopy and its chloride ion complex, l.CI-, by negative ion FAB mass spectroscopy. The structure of 1 was determined by X-ray crystallography. 1 crystallized from acetonitrile in the monoclinic space group P21/c with a = 13.358 (2), b = 26.846 (4), and c = 20.375 A, 0 = 109.694 (S)", V = 7909 AS, and 2 = 4. Data were collected on a Picker FACS-1 diffractometer, using Mo Ka radiation, to a maximum 20 = 45", giving 10 348 unique reflections, and the structure was solved by heavy atom methods. The final discrepancy index was R = 0.044, R, = 0.049 for 5193 independent reflections with I > 34). The chloride ion complex of 1, IClLi, was formed upon treatment of 1 with LiCI. The complexation behavior of 1 in acetone was studied by 199Hg NMR spectroscopy.
