摘要
C17H22N4O4(2+).2I-.H2O, M(r) = 618.2, monoclinic, P2(1)/n, a = 6.772 (3), b = 13.205 (2), c = 25.805 (4) angstrom, beta = 95.83 (3)-degrees, V = 2296 angstrom 3, Z = 4, D(x) = 1.789 Mg m-3, lambda(Mo K-alpha) = 0.7107 angstrom, graphite monochromator, mu = 28.1 cm-1, F(000) = 1208, T = 298 K, R = 0.058 for the 2114 observed reflections. The title compound is a powerful activator of acetylcholinesterase. The positively charged organic cation envelops one I- anion. CNDO calculations show the perturbation of the molecular orbitals by one of the I- anions. Crystal cohesion depends both on hydrogen bonds and electrostatic interactions.
