Abstract
Cesium methylsulfonate, CsCH3SO3, crystallizes in space group Pnma with a = 9.526, b = 6.264, and c = 8.692 Å. Three-dimensional X-ray diffraction data have been collected photographically and refined to give a weighted agreement index (R) of 0.12. The structure is related to, but is not identical with, that of the isoelectronic compound barium sulfate. The CH3SO3− ion has C3v symmetry within the accuracy of this analysis, with S—O = 1.47 ± 0.02, S—C = 1.85 ± 0.04 Å (corrected for thermal motion), O—S—O = 112 ± 1°, and O—S—C = 107 ± 2°. The cesium ion is surrounded by nine oxygen atoms (Cs—O between 3.12 and 3.35 Å) and one methyl group (Cs—C = 3.77 Å).Keywords
