Polymeric structures in the metal complexes of 5-sulfosalicylic acid: The rubidium(I), caesium(I) and lead(II) analogues
Smith, Graham, Wermuth, Urs D., Young, David J., & White, Jonathan M. (2007) Polymeric structures in the metal complexes of 5-sulfosalicylic acid: The rubidium(I), caesium(I) and lead(II) analogues. Polyhedron, 26(14), pp. 3645-3652.
The complexes of 3-carboxy-4-hydroxybenzenesulfonic acid (5-sulfosalicylic acid, H3SSSA) with rubidium(I), caesium(I) and lead(II) have been synthesized and characterized using single crystal X-ray methods at 130 K. The rubidium(I) complex 1, [Rb3(H2SSA)(HSSA)(H2O)4]n, is an unstable hydrate variant of a previously described complex [Rb(H2SSA)(H2O]n, and comprises three independent and different seven-coordinate metal polyhedra interlinked through oxygen donors of the sulfonate, carboxylate and phenolate groups of the 5-sulfosalicylate ligands (one of which is dianionic, the other monoanionic), and one bridging water, giving a three-dimensional hydrogen-bonded framework polymer structure. The anhydrous caesium(I) complex 2 [Cs(H2SSA)]n, which has breen previously described in a room-temperature determination, has a three-dimensional framework polymer structure based on an irregular Cs-O9 repeating unit. Complex 3 with lead(II), [Pb(H2SSA)2(H2O)]n, forms helical step-polymer ribbon sub-structures having an irregular Pb-O7 coordination centre comprising a single monodentate water and six sulfonate-O donors bridging three separate metals. The carboxylic acid and phenol substituent groups of the 5-sulfosalicylate ligand link the ribbons peripherally through hydrogen bonds, giving a three-dimensional layered polymer structure.

Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
