2O,O')dichloridolanthanum(III) dichloride dihydrateAbstract: In the title compound, (H3O)[LaCl2(C2H5N3O2)2(H2O)3]Cl2·2H2O, the La atom is bonded to seven O atoms (arising from two O,O'-bidentate biuret molecules and three water molecules) and two chloride ions in an irregular arrangement. A network of N-H
O, N-H
Cl, O-H
O and O-H
Cl hydrogen bonds helps to establish the packing, leading to a three-dimensional network. The La atom, one Cl atom and four O atoms lie on a crystallographic mirror plane.
