Chiral α-Hydroxy Acids: Racemic 2-Hydroxy-2,3,3-trimethylbutanoic Acid and 2-Hydroxy-2-trimethylsilylpropanoic Acid

Both C₇H₁₄O₃ and C₆H₁₄O₃Si crystallize as racemates from acetone solution, the former incorporating water of crystallization. The crystal structures display extensive intermolecular hydrogen bonding involving the hydroxy and carboxylic acid groups to give polymeric networks.
