In the title compound, [Zn(NCS)(C12H18N2O2)2]NO3, the ZnII ion is chelated by the phenolate O and imine N atoms from two zwitterionic Schiff base ligands and is also coordinated by the N atom of a thiocyanate ligand, giving a distorted trigonal-bipyramidal geometry. Intramolecular N—H⋯O hydrogen bonds are observed in the complex cation. The nitrate anions are linked to the complex cations through N—H⋯O hydrogen bonds.

3-Ethoxysalicylaldehyde (0.2 mmol, 33.2 mg) and N-methylethane-1,2-diamine (0.2 mmol, 14.8 mg) were dissolved in MeOH (10 ml). The mixture was stirred at room temperature for 10 min to give a clear yellow solution. To this solution was added an aqueous solution (2 ml) of ammonium thiocyanate (0.2 mmol, 15.2 mg) and an aqueous solution (3 ml) of Zn(NO3)2.6H2O (0.1 mmol, 29.0 mg) with stirring. The resulting mixture was stirred for another 10 min at room temperature. After keeping the filtrate in air for a week, colourless block-shaped crystals were formed at the bottom of the vessel.
H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C–H distances in the range 0.93–0.97 Å, N–H distances of 0.90 Å, and with Uiso(H) set at 1.2Ueq(C,N) and 1.5Ueq(methyl C). During the
the displacement parameters of atom O6 were restrained to an approximate isotropic behaviour. The contains four solvent accessible voids each with a volume of 53 Å3. But no significant electron density is found in these voids.As part of our investigations into novel urease inhibitors, we have synthesized the title compound, a new ZnII complex. The compound consists of a mononuclear zinc(II) complex cation and a nitrate anion. The Zn atom is chelated by the phenolate O and imine N atoms from two Schiff base ligands, and is coordinated by the N atom from a thiocyanate ligand, forming a trigonal-bipyramid geometry (Fig. 1). The coordinate bond lengths (Table 1) and angles are typical and are comparable with those observed in other similar zinc(II) complexes (Zhang & Wang, 2007; Adams et al., 2003). The amine N atoms of the Schiff base ligands are protonated and take no part in the coordination to the ZnII ion.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As part of our investigations into novel urease inhibitors, we have synthesized the title compound, a new ZnII complex. The compound consists of a mononuclear zinc(II) complex cation and a nitrate anion. The Zn atom is chelated by the phenolate O and imine N atoms from two Schiff base ligands, and is coordinated by the N atom from a thiocyanate ligand, forming a trigonal-bipyramid geometry (Fig. 1). The coordinate bond lengths (Table 1) and angles are typical and are comparable with those observed in other similar zinc(II) complexes (Zhang & Wang, 2007; Adams et al., 2003). The amine N atoms of the Schiff base ligands are protonated and take no part in the coordination to the ZnII ion.
