Dibarium zirconium tetraoxalate trihydrate
Abstract:A new mixed barium zirconium oxalate, triaquatetra--oxalato-dibarium(II)zirconium(IV), Ba2Zr(C2O4)4·3H2O or [Ba2Zr(C2O4)4(H2O)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 C2 symmetry. Packing in the crystal is also assumed through hydrogen bonds.
