Web1 jan. 1984 · In all cases the tartrate ion has its chain of carbon atoms almost exactly in a plane and the C-C02 groups constituting each half of the ion are also practically planar. The planes of C-C02 groups are inclined nearly at 60 to the plane of the carbon atoms. C2 symmetry has therefore been assumed for a tartrate ion in aqueous solution. http://fr.dictionary.education/english/dictionary/tartrate ravin buyout
