Bis{2-ethoxy-6-[2-(ethylammonio)ethyliminomethyl]phenolato}thiocyanatozinc(II) nitrate

H.-R. Guo

Abstract top

The title complex, [Zn(NCS)(C13H20N2O2)2]NO3, consists of a complex mononuclear ZnII cation and a nitrate counter-anion. The ZnII ion is five-coordinate in a trigonal-bipyramidal geometry. The thiocyanate N atom and two O atoms from two Schiff bases define the equatorial plane, and the two imine N atoms from the same two Schiff bases occupy the axial positions, with an N-Zn-N angle of 175.98 (7)°. The amine N atoms of the Schiff base ligands are protonated and are not involved in the coordination to the metal. The dihedral angle between the two substituted benzene rings is 87.7 (2)°. The nitrate counter-ions are linked to the cations through N-H...O hydrogen bonds.

Comment top

The synthesis and structural investigation of Schiff base complexes have attracted much attention due to their interesting structures and wide potential applications (Samanta et al., 2007; Ghosh et al., 2006; Correia et al., 2006; Cai et al., 2006; Zhang et al., 2007). ZnII complexes play an important role in biological systems (Berg & Shi, 1996; Tarafder et al., 2002; Osowole et al., 2008; Chohan & Kausar, 1993). In this paper, the crystal structure of a new ZnII complex, (I), with the Schiff base 2-ethoxy-6-[(2-ethylammonioethylimino)methyl]phenol and thiocyanate as ligands is reported.

The asymmetric unit of (I) (Fig. 1) consists of a mononuclear ZnII complex cation and a nitrate counteranion. The ZnII ion is five-coordinate in a trigonal-bipyramidal geometry, with one thiocyanate N atom and two O atoms from two Schiff bases defining the base-plane, and with two imine N atoms from two Schiff bases occupying the axial positions. The coordination bond lengths and angles (Table 1) are comparable with those found in related structures (Eltayeb et al., 2008; Odoko et al., 2006; Tatar et al., 2002). The dihedral angle between the two substituted benzene rings is 87.7 (2)°. The nitrate counterions are linked to the complex cations through intermolecular N—H···O hydrogen bonds (Table 2, Fig. 2).

Experimental top

The Schiff base was synthesized by condensing N-ethylethane-1,2-diamine with 3-ethoxysalicylaldehyde. The compound (0.236 g, 1.0 mmol), ammonium thiocyanate (0.076 g, 1.0 mmol), and Zn(NO3)2.6H2O (0.297 g, 1.0 mmol) were heated in ethanol (30 ml) for two hours. The resulting yellow precipitate was washed with cold ethanol and dried in air. Yellow single crystals of the complex suitable for X-ray diffraction were obtained by recrystallization in methanol at room temperature over a week.

Refinement top

All H-atoms were placed in calculated positions (C—H 0.93 to 0.97 Å, N—H 0.90 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2 to 1.5Ueq(C) and 1.2Ueq(N). A rotating group model was used for the methyl groups.
