Crystal and molecular structures of four different salts of a dihydroxyacetone phosphate (DHAP) precursor, its dimethyl acetal [2,2-dimethoxy-1,3-propanediol phosphate, C(5)H(13)O(7)P, (MeO)(2)DHAP]: (cha)(2)[(MeO)(2)DHAP].H(2)O (6a), (cha)[(MeO)(2)DHAP] (6b), Na(2)[(MeO)(2)DHAP].5.75H(2)O (6c) and K(2)[(MeO)(2)DHAP].H(2)O (6d), along with the cyclohexylammonium (cha) salt of its phenyl ester (cha)[(MeO)(2)DHAP(Ph)]
