The amino alcohols derivatives are widely used in medicine in treating various types of diseases. They all have a wide range of donor atoms, and form, with metal ions, biologically active coordination compounds with various compositions and properties. In this regard, the accumulation of experimental data on the synthesis of complexes of this class, physicochemical study of their composition and structure are of both scientific and practical interest. The aim of the present paper was to synthesize and determine the crystal structures of acetate-4-bromo2-([(2-hydroxyethylamino) ethylimino] methyl)phenolo (1-)-copper (compound I) and bromo-2-{[2-(2hydroxyethylamino) ethylimino] methyl}-4-nitrophenolo (1 -)-copper (compound II) by X-ray analysis . It has been found that in the studied complexes the molecules of 4-bromo-2-{[2-(2hydroxyethylamino)ethylimino]methyl}phenol and bromo-2-([2-(2-hydroxyethylamino) ethylimino] methyl)-4-nitrophenolo are joined to the four-dentate copper atom through O, N, N, O set of donor atoms with the average distances of Cu-O 1.985 and Cu-N 1.973 Ǻ. In compound (I), the axial vertices of the bipyramid are occupied by the atoms of alcohol oxygen of azomethine and acetate-ion with distances of 2.408 and 2.712 Å respectively. In compound (II) the fifth coordinate is occupied by the bromine atom (CuBr = 2.741 Å). The coordination polyhedron of the central atom in (I) can be considered a distorted tetragonal bipyramid with (4 +1 +1) coordination mode of the copper atom. In complex (II) the coordination polyhedron of the copper atom is a distorted pyramid with the (4 +1) metal coordination mode of the metal (Fig. 2). The copper:ligand ratio is 1:1 in both compounds.Fig. 1. The centrosymmetric dimer of compound (I). Fig. 2. The molecular structure of compound (II).In the crystal of compound (I) centrosymmetric dimers are formed due to the O-H ... O hydrogen bonds (Fig. 1). Cu ... Cu distances in the dimer is 5.47 Ǻ. Other non-valent interactions in crystals (I) and (II) are discussed .
