1,1-Diaqua-2,3,4,5,6-pentaisopropoxy-1-nickeladodecaborane
Abstract
The title mononickeladodecaborane cluster, [NiB11H6(OC3H7)5(H2O)2], has been synthesized by the reaction of dichlorobis(triphenylphosphine)nickel(II) with triethylammonium nido-undecaborane(14) in 2-propanol. The NiIV atom is connected to five atoms of the boron cage to form a closo 12-vertex {NiB11} icosahedral skeleton. All of the H atoms on the five B cage atoms connected to the Ni atom are substituted by isopropoxy groups. The NiIV atom is also bonded to two water molecules. The molecules form dimers through intermolecular hydrogen-bond interactions.
