The structure of the hydrogensulfite ion has been determined for the first time in CsHSO 3 which crystallizes in space group R3m with a = 4.6721 (7) ,/k, a = 85.31 (1) °, Z = 1. The absolute configuration of the structure was refined to R = 0-014 for 506 independent reflections. The S atom has tetrahedral coordination, with three pyramidal S-O bonds and an S-H bond in the fourth direction. The S-O distance is 1.454 (2),~, and the O-S-O angle 113.1 (2) °. The bond distance is similar to that in the SO ]- ion, while it differs markedly from that in the SO]- ion. The Cs + ion is nine-coordinated with Cs-O distances of 3.231 (4)3.249 (4) A. |
