Abstract
The addition compound of benzaldehyde and potassium bisulfite crystallizes in the monoclinic space group P21⁄c, with four formula units per unit cell with the dimensions: a=16.37, b=6.07, c=9.12 A and β=103.4°. The structure was determined by the heavy atom method, and the structural parameters were refined by least-squares method with a block-diagonal approximation. The analysis showed that the addition product is potassium α-hydroxybenzylsulfonate, C6H5CH(OH)SO3−·K+. Three S-O bond distances range from 1.43 to 1.46 A; the average of three O-S-O bond angle is 112.1°, while that of three O-S-Cα’s is 106.7°. The bond distance of S-Cα, 1.831 A, is significantly longer than those in other sulfonates so far reported. The potassium ion is surrounded by nine oxygen atoms; the K-O distances being from 2.73 to 3.27 A.
