Crystal structure of lanthanum(III) oxalate decahydrate

Article abstract of DOI:10.1007/BF01161053

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) Angstroem, β = 114.52(4) deg, and Z = 2.The structure (R = 0.029 for 3190 Mo Kα 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 η⁴ chelating oxalate groups and three aqua ligands with La-O distances in the range 2.518(4)-2.622(4) Angstroem.The remaining water molecules are disordered over seven principal sites in the intervening space.
