Strychnine-8-Ammonio-2-naphthalenesulfonate-water (1/1/3.5): The First Structure of a Strychnine Compound with a Zwitterionic Species
Smith, Graham, Wermuth, Urs D., Young, David J., & Healy, Peter C. (2006) Strychnine-8-Ammonio-2-naphthalenesulfonate-water (1/1/3.5): The First Structure of a Strychnine Compound with a Zwitterionic Species. Journal of Chemical Crystallography, 36, pp. 805-811.
The crystal structure of the 1:1 adduct hydrate of strychnine with 1,7-Cleve’s acid (8-amino- 2-naphthalenesulfonic acid), namely strychnine-8-ammonio-2-naphthalenesulfonate-water (1/1/3.5) has been determined and provides a unique example of a neutral association involving strychnine and an achiral zwitterionic acid species, previously unobserved in the structures of either strychnine or brucine addition compounds. Crystals are orthorhombic, space group P212121, with Z=4 in a cell with dimensions a=10.4484(8), b=30.850(3), c=9.4998(11) A° . Hydrogen bonding involving all available proton-donor and acceptor sites on all species gives rise to a three-dimensional framework polymer structure. The crystallographic literature for strychnine and brucine and their compounds is also reviewed.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
