Abstract Scope |
This talk will detail the synthesis and the crystal structures of the new quaternary Zintl phases Na2CaCdSb2, Na2SrCdSb2 and Na2EuCdSb2. They are isostructural and their non‐centrosymmetric structure is with the space group Pmc21 (Pearson code oP12). All structural work is carried out via
single‐crystal X‐ray diffraction methods. The structure features [CdSb2]4– layers of corner shared CdSb4 tetrahedra, which are stacked along the b‐crystallographic axis and are separated by cations. The results from the structure refinements suggest that in addition to full cation ordering, which is typical for this structure, there also exist a possibility for an accommodation of a small degree of cation disorder. |
