Abstract
Abstractβ-ethylenediaminetetraacetic acid crystallizes in the monoclinic system:a = 13·273(4),b = 5·575(7),c = 16·110(6) Å, β = 96·26(3),Z = 4,C2/c. The structure has been determined by direct methods with CuKα diffractometer data, and refined by full-matrix least squares toR = 0·057 for 755 observed reflexions.The molecule exists in acis conformation and possesses two-fold symmetry, the diad axis passing through the central C—C bond. The nitrogen atom is protonated, and takes part in a bifurcated intramolecular hydrogen bond. A short (2·46 Å) hydrogen bond links the oxygen atoms of adjacent molecules.
