STRUCTURE OF PERCHLORATO[(2S,6R,9S,13R)-2,6,9,13-TETRAAZATETRADECANE]COPPER(II) PERCHLORATE

[Cu(ClO4)(C10H26N4)]ClO4, M(r) = 464.79, monoclinic, P2(1)/n, a = 7.440 (1), b = 143678 (3), c = 16.903 (3) angstrom, beta = 90.845 (1)-degrees, V = 1845.7 angstrom 3, Z = 4, D(x) = 1.670 Mg m-3, lambda(Mo K-alpha) = 0.7093 angstrom, mu = 1.52 mm-1, F(000) = 963.80, T = 298 (4) K, R = 0.049, wR = 0.074 for 2275 significant reflections. The coordination about Cu(II) is distorted square pyramidal with the tetraamine equatorial and the O atom of a perchlorate ion axial. The Cu atom is slightly (0.014 angstrom) out of the square coordination plane towards the O atom of the axial coordinated perchlorate ion. The configurations of the four chiral N centres are (2S,6R,9S,13R) and/or (2R,6S,9R,13S). In the quadridentate ligand the terminal six-membered chelate rings are in a stable chair form and the central five-membered chelate ring is in an unstable skew form.
