摘要

Aminoalkanol and aroxyalkyl derivatives are known as potential anticonvulsants. Two new salts, namely bis{( R,S )‐ N ‐[2‐(2,6‐dimethylphenoxy)ethyl]‐1‐hydroxypropan‐2‐aminium} succinate ( 1s ), C 13 H 22 NO 2 + ·0.5C 4 H 4 O 4 2? , and bis{( S )‐(+)‐ N ‐[2‐(2,6‐dimethylphenoxy)ethyl]‐1‐hydroxypropan‐2‐aminium} succinate ( 2s ), C 13 H 22 NO 2 + ·0.5C 4 H 4 O 4 2? , have been prepared and characterized by single‐crystal X‐ray diffraction. The N atoms are protonated by proton transfer from succinic acid. Salt 1s crystallizes in the space group P 2 1 / n with one cation and half an anion in the asymmetric unit across an inversion centre, while ( 2s ) crystallizes in the space group P 2 1 with four cations and two anions in the asymmetric unit. The hydroxy group of the cation of 1s is observed in two R / S disorder positions. The crystals of these two salts display similar supramolecular architectures ( i.e. two‐dimensional networks), built mainly by intermolecular N + —H…O δ? and O—H…O δ? hydrogen bonds, where `δ?' represents a partial charge. The succinate anions are engaged in hydrogen bonds, not only with protonated N atoms, but also with hydroxy groups.
