Abstract

In the title compound, C9H8N+.C6H7O7-, the dihydrogen citrate anions form a convoluted two-dimensional hydrogen-bonded substructure through head-to-tail interactions with the interstitial pi-stacked quinolinium cations linked to it peripherally through cyclic R21(5) N+-H...O(carboxyl/hydroxyl) hydrogen-bond interactions. The loss of the proton from one of the beta-carboxylic acid groups of the citric acid generates a chiral centre in the anion, but these form a racemate in the centrosymmetric crystal structure.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
