Organically pillared layer framework of [Eu(NH₂–BDC)(ox)(H₃O)]

Abstract

An organically pillared EuIII–oxalate–carboxyl­ate framework structure with [Eu(NH2—BDC)(ox)(H3O)] topology is reported. The non-porous three-dimensional structure is constructed from two-dimensional layers of EuIII–carboxyl­ate–oxalate, which are pillared by NH2—BDC2− pillars. The basic structural unit of the layer is an edge-sharing dimer of TPRS-{EuIIIO9}, which is assembled through the ox2− moiety. The intra­layer void is partially occupied by TPR-{EuIIIO6} motifs.
