Solvothermal Synthesis, Crystal Structure and Properties of a New Organic Templated Lanthanum Sulfate [C4N3H16][La(SO4)3(H2O)]
2008
A new organic templated lanthanum sulfate [C4N3H16][La(SO4)3(H2O)] (1) has been solvothermally synthesized by using n-butanol as solvent. The colorless block crystals were characterized by IR, TGA, ICP, and XRD. The structure was determined by single-crystal X-ray diffraction: Monoclinic, P21/c, a = 10.8878(19), b = 15.478(3), c = 9.9639(18) A, β = 114.062(2)°, V=1533.2(5) A3, Z = 4]. Crystal structure analysis shows that the one dimensional chain of 1 consists of the LaO9 polyhedra and the sulfate groups. Coordination water molecules link adjacent chains by using hydrogen bonds to generate 2D layers, whereas the organic amines are inserted between the layers. The formation of 1 demonstrates that solvents play an important role during the synthesis.
