Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In the title metal–organic framework (MOF), [La(C₈H₈N₂O₆)(C₂O₄)_0.5(H₂O)]_{<italic>n</italic>}, the La^III cation is coordinated by eight O atoms in a square antiprismatic configuration. Each La^III cation is connected to adjacent La^III cations by bridging 2, 5‐dioxopiperazine‐1, 4‐diacetate (PODC²⁻) and oxalate (lying about an inversion centre) ligands, generating two‐dimensional grid layers. The layers are further linked <italic>via</italic> the carboxylate groups of the PODC²⁻ ligands in <italic>syn</italic>–<italic>syn</italic> and <italic>syn</italic>–<italic>anti</italic> modes, resulting in a three‐dimensional framework with a short Schläfli vertex notation of {4⁷.6³}{4⁷.6⁷.8}.</p> </abstract>
