An octa-nuclear nickel(II) pyrazolate cluster with a cubic Ni₈ core and its methyl- and n-octyl-functionalized derivatives.

ABSTRACT: The mol-ecular and crystal structure of a discrete [Ni₈(μ₄-OH)₆(μ-4-Rpz)₁₂]^2- (R = H; pz = pyrazolate anion, C₃H₃N₂ ^-) cluster with an unprecedented, perfectly cubic arrangement of its eight Ni centers is reported, along with its lower-symmetry alkyl-functionalized (R = methyl and n-oct-yl) derivatives. Crystals of the latter two were obtained with two identical counter-ions (Bu₄N⁺), whereas the crystal of the complex with the parent pyrazole ligand has one Me₄N⁺ and one Bu₄N⁺ counter-ion. The methyl derivative incorporates 1,2-di-chloro-ethane solvent mol-ecules in its crystal structure, whereas the
