A new mixed barium zirconium oxalate, triaquatetra‐μ‐oxalato‐dibarium(II)zirconium(IV), Ba 2 Zr(C 2 O 4 ) 4 ·3H 2 O or [Ba 2 Zr(C 2 O 4 ) 4 (H 2 O) 3 ] n , has been synthesized. The complex is built from eightfold‐coordinated Zr atoms and eleven‐ and sixfold‐coordinated Ba atoms, linked by oxalate groups. The Zr atom, the two Ba atoms and one water O atom lie on crystallographic twofold axes, so that each coordination polyhedron has imposed C 2 symmetry. Packing in the crystal is also assumed through hydrogen bonds.
