Abstract

<p>The structure of (1-(2-(2-aminoethylamino)ethylimino)methyl-2-napththolato-<i>O,N,N',N"</i>)bromozinc(II), [Zn(naden)Br], containing a new Schiff base ligand, naden, was solved by Patterson and Fourier techniques and refined anisotropically to <i>R</i> = 0.047 for 1&nbsp;426 unique observed reflections. The complex crystallizes in the space group <i>Pbca</i> with lattice parameters <i>a</i> = 14.024(1), <i>b</i> = 10.699(1), <i>c</i> = 21.635(2) Å, <i>Z</i> = 8. The structure of [Zn(C<sub>15</sub>H<sub>18</sub>N<sub>3</sub>O)Br] complex molecule consists of two six-membered aromatic rings and one six-membered and two five-membered chelate rings. The distorted coordinate polyhedron around Zn atom is formed by N1, N2, N3 and O atoms of the naden ligand and Br anion. Unusually short C-C bond in five-membered rings as well as small N-C-C-N torsion angles and somewhat large C4-C3-N2 and N2-C2-C1 angles are probably connected with intense thermal vibrations of C2 and C3 atoms. The structure is hold together by weak hydrogen bonds.
