Abstract La2(C2O4)3·10H2O crystallizes in space groupP21/c (No. 14) witha=11.382(6),b=9.624(5),c=10.502(8) Å,β=114.52(4)°, andZ=2. The structure (R=0.029 for 3190 MoKα data) is composed of two-dimensional networks of edge-sharing 1∶5∶3 coordination polyhedra matching the (020) set of planes, each La(III) atom being surrounded by threeη 4 chelating oxalate groups and three aqua ligands with La-O distances in the range 2.518(4)–2.622(4) Å. The remaining water molecules are disordered over seven principal sites in the intervening space.
