The zwitterionic dicarboxylate 1,1′-[(2,3,5,6-tetramethylbenzene-1,4-diyl)bis(methylene)]bis(pyridin-1-ium-4-carboxylate) (L) has been reacted with uranyl nitrate under solvo-hydrothermal conditions and in the presence of KReO$_4$ to give the complex [UO$_2$(L)(OH)(H$_4$O)](ReO$_4$) (1). This compound crystallizes as a cationic, monoperiodic coordination polymer with ReO${_4^-}$ as a simple counterion. The daisy-chain polymer is based on dinuclear rings built by the convergent zwitterionic ligands, these rings being linked to one another by double hydroxide bridges. In addition to a Coulombic interaction with a pyridinium ring, ReO4– is involved in one OH(water)⋅⋅⋅O and four CH⋅⋅⋅O interactions, and it is thus nestled in a cavity formed by three chains, seemingly with some selectivity over nitrate and chloride anions also present in the reaction mixture. This result illustrates the interest of zwitterionic dicarboxylates in building cationic assemblies able to trap ReO${_4^-}$, a surrogate for the radioactive TcO${_4^-}$, an anion of environmental relevance.
