title: Redetermination of aqua-(dihydrogen ethyl-enediamine-tetra-acetato-κO,O',N,N',O'')nickel(II).
abstract: The crystal structure of the title compound, [Ni(C(10)H(14)N(2)O(8))(H(2)O)] or [Ni(H(2)edta)(H(2)O)] (H(4)edta is ethyl-ene-diamine-tetra-acetic acid), originally determined by Smith & Hoard [J. Am. Chem. Soc. (1959), 81, 556-561] has been redetermined to a significantly higher precision. The Ni(II) atom is coordinated in a distorted octa-hedral geometry by two N atoms and three O atoms from three carboxyl-ate groups of the H(2)edta(2-) ligand and by an O atom of a water mol-ecule. The complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds into layers perpendicular to [100].
