nondissymmetric
a term formerly used to describe an achiral molecule that possesses an alternating axis of symmetry but that (unlike a symmetric molecule) lacks a simple axis of symmetry; the converse of dissymmetric. An important example is citric acid, which has a one-fold alternating axis but no simple axis; thus its pair of carboxymethyl groups on carbon-3 are not geometrically equivalent. See also prochiral.
