The title compound, C(13)H(11)NO(4)·H(2)O, is a monohydrate of a betaine exhibiting a positively charged N-substituted isoquino-line group and a deprotonated carboxyl group. In the crystal, mol-ecules are connected via short O-H⋯O hydrogen bonds between protonated and deprotonated carboxyl groups into chains of either R or S enanti-omers along [001]. These chains are additionally connected by hydrogen bonding between water mol-ecules and the deprotonated carb-oxy groups of neighbouring mol-ecules.
标题化合物C(13)H(11)NO(4)·H(2)O是一种甜菜碱的一水合物,具有带正电荷的N-取代异喹啉基团和去质子化的羧基。在晶体中,分子通过质子化和去质子化羧基之间的短O-H⋯O氢键连接成沿[001]方向的R或S对映体链。这些链还通过水分子与相邻分子的去质子化羧基之间的氢键进一步连接。
