摘要
采用SrCO3与Rh在空气中固相反应制备了新型高温相β-SrRh2O4。化合物在空间群P63c中结晶，Z = 1，其中a = 3.0626(2) Å， c = 11.3996(7) Å。该结构由具有AABB氧层序列的cd12型共享边缘的RhO6八面体层组成。在三角棱柱配位中，锶被发现在两个可用的层间位置部分占据。
Structure of β-SrRh2O4 from X-ray and neutron powder diffraction
β-SrRh2O4, a novel high temperature phase, is prepared as black powder by solid state reaction of SrCO3 with Rh in air. The compound crystallises in the space group P63c, Z = 1, with a = 3.0626(2) Å and c = 11.3996(7) Å. The structure consists of Cd12-type layers of edge sharing RhO6 octahedra with an AABB oxygen layer sequence. Strontium is found in partial occupation of both available interlayer sites, in trigonal prismatic coordination.
