Description
The crystal structure of stoichiometric La4CO3O10.00 is of the Ruddlesden-Popper type and contains slabs of triple perovskite layers separated by rock salt layers, the composition corresponding to n = 3 in the An+1BnO3n+1 series. On heating, the slightly orthorhombically deformed structure converts into a tetragonal one at around 840 K. Antiferromagnetic ordering occurs below TN ≅ 10 K. Crystal structure data from powder neutron diffraction are presented. Slight line broadening of some X-ray reflections and a few, weak additional neutron reflections indicates that the true symmetry is lower than Fmmm. (authors)
