Sumario:The non-porous three-dimensional structure of poly[(μ(5)-2-amino­benzene-1,4-di­carboxyl­ato)(μ(6)-oxalato)(oxomium)europium(III)], [Eu(C(8)H(5)NO(4))(C(2)O(4))(H(3)O)](n) or [Eu(III)(NH(2)–BDC)(ox)(H(3)O)](n) (NH(2)–BDC(2−) = 2-amino­terephthalate and ox(2−) = oxalate) is constructed from two-dimensional layers of Eu(III)–carboxyl­ate–oxalate, which are connected by NH(2)–BDC(2−) pillars. The basic structural unit of the layer is an edge-sharing dimer of TPRS-{Eu(III)O(9)}, which is assembled through the ox(2−) moiety. The intra­layer void is partially occupied by TPR-{Eu(III)O(6)} motifs. Weak C—H⋯O and strong, classical intra­molecular N—H⋯O and inter­molecular O—H⋯O hydrogen-bonding inter­actions, as well as weak π–π stacking inter­actions, affix the organic pillars within the framework. The two-dimensional layer can be simplified to a uninodal 4-connected sql/Shubnikov tetra­gonal plane net with point symbol {4(4).6(2)}.
