Abstract
The crystal structure of a monoclinic form of the title compound, C10H18N2O82+·2Cl−·3H2O or (H6edta)Cl2·3H2O, is reported. The first published form had space group P1 [Mistryukov, Mikhailov, Sergeev, Zhuravlov, Schelokov, Chernov, Fodorov & Brekhovskikh (1987). Dokl. Akad. Nauk SSSR, 295, 1390–1393], while the structure reported here has P2/c. A crystallographic twofold rotation axis passes through the mid-point of the central C—C bond of the cation; another twofold axis passes through one water O atom. In the crystal structure, the (H6edta)2+ and Cl− ions and water molecules are linked via hydrogen bonds, forming two-dimensional networks. The NH groups and carbonyl O atoms form trifurcated hydrogen bonds.
