Abstract
A 3d–4f heterometallic coordination polymer, {[EuCu(C2O4)(na)2] · 2H2O} n (1) [Hna=nicotinic acid], has been synthesized by hydrothermal reaction of lanthanide oxides, Cu(I), and pyridine-2,3-dicarboxylic acid. 1 features a 3-D pillar-layered coordination framework constructed from two-dimensional lanthanide-carboxylate layers and Cu(na) pillars. Interestingly, the na ligand was obtained by the in situ decarboxylation of pyridine-2,3-dicarboxylic acid.
