摘要：

La2(C2O4)3 . 10H2O crystallizes in space group P21/c (No. 14) with a = 11.382(6), b = 9.624(5), c = 10.502(8) angstrom, beta = 114.52(4)degrees, and Z = 2. The structure (R = 0.029 for 3190 Mo K-alpha 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 three eta-4 chelating oxalate groups and three aqua ligands with La-O distances in the range 2.518(4)-2.622(4) angstrom. The remaining water molecules are disordered over seven principal sites in the intervening space.
