Structure of N,N-bis(2-aminoethyl)diethylenetriamine(chloro)cobalt(III) chloride perchlorate hydrate

[Co(C8H23N5)Cl]Cl(ClO4).H2O, M(r) = 436.6, monoclinic, P2(1)/n, a = 14.769 (3), b = 13.558 (1), c = 9.056 (2) angstrom, beta = 105.281 (3)-degrees, V = 1749 (1) angstrom 3, Z = 4, D(m) = 1.66 (1), D(x) = 1.658 g cm-3, lambda(Mo K-alpha) = 0.7107 angstrom, mu = 14.67 cm-1, F(000) = 904, T = 293 K, final R = 0.046 for 5092 counter-measured reflections. The structure consists of octahedral cations [Co(trenen)Cl]2+ with one chloride and one perchlorate ion together with one water molecule involved in hydrogen bonding in the gross structure. The mean Co-N distance is 1.960 (18) and Co-Cl is 2.267 (1) angstrom. The Co-N(sec) distance [1.932 (3) angstrom] is significantly shorter than the other Co-N distances and indicates stronger binding to the secondary N atom.
