WebJan 30, 2024 · The positions of the oxygen atoms are known definitely from X-ray investigation. These form an open-work structure in which each oxygen is surrounded tetrahedrally by four others, the whole system having hexagonal symmetry. The positions of the hydrogen atoms between each pair of oxygens are not known with certainty, perhaps … WebOpen navigation menu. Close suggestions Search Search. en Change Language Change Language

The Ln 2 O 2 S 2 structure, (Ln = rare earth), determined by X-ray and neutron data may be described by alternate layers perpendicular to the C-axis with (Ln 2 O 2) 2+ and (S-S) 2− composition. The (S-S) 2− ions are ordered in a plane layer but these planes are disordered along the C-axis. The structure is related to other rare ...
