摘要：

C15H25N2O3+.Cl-, M(r) = 316.9, monoclinic, P2(1)/c, a = 13.228 (9), b = 11.065 (8), c = 11.556 (10) angstrom, beta = 96.32 (7)-degrees, V = 1681 (2) angstrom 3, Z = 4, D(m) = 1.25 (1), D(x) = 1.252 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.22 mm-1, F(000) = 652, T = 293 K, final R = 0.045 for 2708 unique observed reflections. The structure consists of discrete cations connected in pairs by hydrogen-bonded chloride anions. The dimethylammonium group is oriented gauche with respect to the carbamate moiety, and the ethoxy group is approximately coplanar with the aromatic system. While the lone pair of electrons of the ethereal O atom is definitely delocalized through the adjacent phenyl ring, the results do not reveal any significant conjugation of the carbamate moiety with the aromatic system.
