Abstract Single crystals of two new strontium iron rhodates, SrFe 0.71Rh 0.29O 3 and Sr 4Fe 0.73Rh 2.27O 9, have been grown and structurally characterized. Single crystals of SrFe 0.71Rh 0.29O 3 and Sr 4Fe 0.73Rh 2.27O 9 were grown from potassium carbonate melts. SrFe 0.71Rh 0.29O 3 crystallizes in the cubic perovskite structure, space group Pm 3 ̄ m , with a=3.9027(6) Å. Sr 4Fe 0.73Rh 2.27O 9 crystallizes with trigonal symmetry in the space group P321, a=9.6091(2) Å and c=7.9448(2) Å, and is structurally related to the 2H-hexagonal perovskites. Sr 4Fe 0.73Rh 2.27O 9 contains two independent 1-D chains of face-sharing polyhedra with a sequence of two RhO 6 octahedra and one Fe/RhO 6 trigonal prism and strontium cations separating the chains. The growth conditions, structures and magnetic properties of these compounds are discussed.
