Abstract
A new compound containing the tetraphenylphosphonium cation and the nickel(III) bisdicarbollyl anion, [(C6H5)4P][Ni(B9C2H11)2]⋅CCl4, was synthesized and investigated by XRD at room temperature (295 K). Crystal data: C29H42B18PCl4Ni, M = 816.69, monoclinic, space group P2/с; unit cell parameters a =
13.5873(6) Å, b = 7.1475(2) Å, c = 20.7829(8) Å, β = 94.4595(13)°, V = 2012.2(2) Å3, Z = 2, dcalc = 1.348 g/cm3. The structure was solved by direct and Fourier methods and refined by the full-matrix least squares method in an anisotropic (isotropic for H) approximation to the final R1 = 0.0466 for 3055 Ihkl ≥ 2σI of 23,655 reflections collected and 5618 independent Ihkl (Bruker X8 APEX diffractometer, λMoKα).
