Abstract
The dimeric condensation product of lactic acid, namely (S,S)-2-[(2-hydroxypropanoyl)oxy]propanoic acid, C(6)H(10)O(5), (I), crystallizes with two independent molecules in the asymmetric unit, which both have an essentially planar backbone. The trimeric condensation product, namely (S,S,S)-3-hydroxybut-3-en-2-yl 2-[(2-hydroxypropanoyl)oxy]propanoate, C(9)H(14)O(7), (II), has one molecule in the asymmetric unit and consists of two essentially planar
