Abstract

Structure determinations of the alums CsM[SO4]2·12H2O have been carried out for M = rhodium(III) and iridium(III), providing the first structurally characterized examples of the hexa-aqua-rhodium(III) and -iridium(III) species. Structures were determined at 295(1) K and refined to R= 0.034 and 0.028 for 546 and 696 independent ‘observed’ reflections for Rh and Ir respectively. Crystals are cubic, space group Pa3 with a= 12.357(5) and 12.395(3)Å respectively; Rh–O is 2.016(3) and Ir–O 2.041(3)Å. Both alums are of the α type. Single-crystal Raman spectra of the S–O stretching vibrations are reported which distinguish between the α and β caesium alums.
