Аннотация: A family of Ln2CrO6 (Ln=Pr, Nd, Sm-Tb) compounds has been re-investigated using powder X-ray diffraction and IR spectroscopy. The structure of β-Nd2CrO6β-[Nd2O2](CrO4) is similar to that of the slag compound [Ba2F2](S6+O3S2-). Its structural architecture is also related to other layered α- and γ-[Ln2O2](AO4) species (A=S, Cr, Mo), Показать полностьюshowing various orientations of the tetrahedral anions within the interlayer space. © 2018 Walter de Gruyter GmbH, Berlin/Bos
