Jg. Kester et al., SYNTHESIS AND PROPERTIES OF COPPER AND NICKEL-COMPLEXES OF THE GENERAL FORMULA (B11H11)(2)M(N-) - CRYSTAL-STRUCTURE OF [(N-BU)(4)N](3)[CU(B11H11)(2)], Inorganic chemistry, 33(24), 1994, pp. 5438-5442
Reaction of Me(3)NH[B11H14] in aqueous NaOH with CuO or NiCl2 formed t
he metallaborane anions Cu(B11H11)2(3-) Ni(B11H11)(2)(4-), respectivel
y. NMR, XPS, and cyclic voltammetry results on some of these compounds
are reported. A single-crystal X-ray structure determination of [N(n-
Bu)(4)](3)[Cu(B11H11)(2)] has been completed (space group Pcnb, a = 43
.652(30) Angstrom, b = 23.221(13) Angstrom, c = 13.608(7) Angstrom, Z
= 8).
