Abstract

In the crystal structure of the 1:1 title salt, C(4)H(12)NO(2) (+)·C(6)H(4)BrO(-), hydrogen-bonding inter-actions originate from the ammonium cation, which adopts a syn conformation. A gauche relationship between the C-O and C-N bonds of the 2-hy-droxy-ethyl fragments also facilitates O-H⋯O inter-actions of bis-(2-hy-droxy-eth-yl)ammonium cation chains to phenolate O atoms. The resulting double-ion chains along [100] are further linked by N-H⋯O inter-actions, forming chains parallel to [110].
