Abstract:  Crystals of Ni2 ((S*, S*)-EDDS) • 10H2O are monoclinic with lattice parame­ters a = 3.065(l)nm, b = 0.9915(5) nm, с = 1.5883(5) nm, 0 = 110.76(2)°, V = 4.5132nm3 , the space group is C2/c, Z = 8. The crystal density is Do= .748 Mgnr-3 , Dc = 1.72 Mgn-3 , CuKα (λ=0.15418 nm) radiation, μ=2.73 mm-1 , the relative molecular mass is Mr = 585.84. The structure was solved by the heavy atom method and refined by the least squares to R = 0.072 for 1810 observed diffractions. The structure consists of [Ni(l)-EDDS]2- complex anions, [Ni(2)(H20)6 ]2+ cations, and crystal water molecules. Both coordination polyhedrons of Ni atom are distorted octahedrons. The coordina­tion polyhedron of Ni(l) atom is formed by two nitrogen atoms of ethylenediamine moiety and by four oxygen atoms of carboxyl groups of EDDS. The complex anion has an (OC-6-13-A) absolute configuration for the (S, S) absolute configuration of the ligand.
