The reaction of aluminium(III) sulfate with piperazinediium pyridine-2,6-dicarboxylate, (pipzH2)(pydc), where pipz is piperazine and pydcH2 is pyridine-2,6-dicarboxylic acid, in aqueous solution leads to the formation of the title complex, (C4H12N2)1/2[Al(H2O)6](SO4)24H2O. The crystal structure of this compound has been published previously [Bataille (2003), Acta Cryst. C59, m459–m461], and our report is a redetermination of the structure at 100 K. As previously observed, intermolecular O—H O and N—H O hydrogen bonds result in the formation of a three-dimensional network and a supramolecular structure.
