✦ Synopsis

3-SrRh204 , 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) A and c = 11.3996(7) A. The structure consists of CdI2-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.
