STRUCTURE OF (4-AMINO-2,2,6,6-TETRAMETHYLPIPERIDINYL-1-OXY)-BIS(HEXAFLUOROACETYLACETONATO)(METHANOL)NICKEL(II) METHANOL SOLVATE

[Ni(C5H2F6O2)2(C9H17N2O)(CH3OH)].-CH3OH, M(r) = 707.2, monoclinic, P2(1)/n, a = 12.125 (3), b = 12.379 (3), c = 20.438 (5) angstrom, beta = 92.07 (2)-degrees, V = 3066 (1) angstrom 3, D(x) = 1.532 Mg m-3, Z = 4, mu = 0.743 mm-1, lambda(Mo K-alpha) = 0.71073 angstrom, F(000) = 1440, T = 298 K, R = 0.0678 and wR = 0.0912 for 2365 averaged reflections with I > 3-sigma(I). The Ni atom in this structure possesses an octahedral geometry and forms bonds to two equatorial F6AcAc ligands, one molecule of methanol and the nitroxyl radical. Coordination of the nitroxyl is through the N atom of the amine group at a distance of 2.075 (6) angstrom. There are no unusual intermolecular contacts and the asymmetric unit contains a molecule of methanol.
