A new 3d–4f heterometallic coordination framework, {[Eu(ox)(H 2 O) 4 ] · [CuBr(2‐pzc) 2 ] · 4H 2 O} ( 1 ) [ox = oxalate; 2‐pzc = pyrazine‐2‐carboxylate] was synthesized and characterized by elemental analysis, IR spectroscopy and thermal analysis, as well as single‐crystal X‐ray diffraction. Complex 1 represents one 3D supramolecular heterometallic coordination framework that is assembled from rare lanthanide‐ox anionic chains and CuBr(2‐pzc) 2 cationic units through hydrogen bonds.
