Structure of (-)-1-phenylethylammonium hydrogen (+)-tartrate.
C8H12N+.C4H5O6-, Mr = 271.27, monoclinic, P21, a = 6.352 (2), b = 14.195 (5), c = 7.507 (2) A, beta = 107.08 (2) degrees, V = 647.0 (8) A3, Z = 2, Dx = 1.39 g cm-3, lambda (Mo K alpha) = 0.71069 A, mu (Mo K alpha) = 1.05 cm-1, F(000) = 288, T = 294 K, R = 0.037 for 941 observed reflections [F greater than 2 sigma (F)]. This (+)-tartrate structure is very similar to its meso-tartrate analogue. O(6) occupies an unusual antiperiplanar position relative to the carboxyl group. A strong hydrogen-bond network stabilizes the crystal packing.
