STRUCTURE OF AQUA(N,N-BIS[2-(2-PYRIDYL)ETHYL]BENZYLAMINE)BIS(TRIFLUOROMETHANE-SULFONATO)NICKEL(II)

[Ni(bpeb)(CF3SO3)2(H2O)], C23H23F6N3NiO6S2, M(r) = 692.34, orthorhombic, Pca2(1), a = 19.013 (6), b = 8.502 (2), c = 17.764 (7) angstrom, V = 2871 (2) angstrom 3, Z = 4, D(x) = 1.60 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.91 mm-1, F(000) = 1416, T = 295 K, R = 0.0505 for 1674 unique observed [F greater-than-or-equal-to 3-sigma(F)] reflections and 265 parameters. [Ni(bpeb)(CF3SO3)2(H2O)] has a pseudooctahedral coordination geometry with Ni-N bond distances varying from 2.073 (8) angstrom for one of the pyridine N atoms to a high of 2.134 (7) angstrom for the amine N atom. The three Ni-O bond distances vary from 2.129 (6) angstrom for one coordinated CF3SO3 to 2.185 (5) angstrom for the other coordinated CF3SO3. The bond angles around the central Ni atom are somewhat distorted from ideal with the smallest O-Ni-O angle being 80.7 (3)-degrees, between the oxygen of the water and one CF3SO3, and the largest N-Ni-N angle being 97.0 (3)-degrees, between one pyridine N atom and the coordinated amine.
