Crystal structures of sodium-, lithium-, and ammonium 4,5-dihydroxybenzene-1,3-disulfonate (tiron) hydrates

Abstract

The first solid-state structures of the Na+, Li+, and NH4 + salts of the tiron dianion are reported. The structures reveal significant changes in local and long-range ionic inter­actions with variation of the cation, with consequences for fields as disparate as bioinorganic chemistry and fuel cell technologies.
