本文报道了L的两个化合物--酒石酸和喹啉的结构。在130 K下测定了质子转移化合物酒石酸喹啉氢(2R，3R)-酒石酸一水合物C9H8N+.C4H5O6-.H2O，(I)和与喹诺酸的无水非质子转移加合物-双(喹啉-2-羧酸)(2R，3R)-酒石酸，2C10H7NO2.C4H6O6，(II)，化合物(I)具有由头尾氢键的酒石酸氢键离子和水分子形成的三维蜂窝状结构。Pi键合的喹啉阳离子的堆叠容纳在通道内，并在外围与通道氢键连接。化合物(II)具有基于拟中心对称的头尾氢键环状二聚体的二维网络结构，该环状二聚体包含通过酒石酸分子相互连接的两性离子奎纳酸物种。
The structures of two compounds of L-tartaric acid with quinoline, viz. the proton-transfer compound quinolinium hydrogen (2R,3R)-tartrate monohydrate, C9H8N+.C4H5O6-.H2O, (I), and the anhydrous non-proton-transfer adduct with quinaldic acid, bis(quinolinium-2-carboxylate) (2R,3R)-tartaric acid, 2C10H7NO2.C4H6O6, (II), have been determined at 130 K. Compound (I) has a three-dimensional honeycomb substructure formed from head-to-tail hydrogen-bonded hydrogen tartrate anions and water molecules. The stacks of pi-bonded quinolinium cations are accommodated within the channels and are hydrogen bonded to it peripherally. Compound (II) has a two-dimensional network structure based on pseudo-centrosymmetric head-to-tail hydrogen-bonded cyclic dimers comprising zwitterionic quinaldic acid species which are interlinked by tartaric acid molecules.
