Ethanolamine(1 mmol, 0.059 ml) was dissolved in hot methanol (10 ml) and added in portions to a methanol solution(3 ml) of o-vanillin (1 mmol, 152.14 mg). The mixture was then stirred at 323 K for 2 h. Subsequently, an aqueous solution(2 ml) of zinc acetate dihydrate(1 mmol, 219.5 mg) was added dropwise and stirred for another 5 h. The solution was held at room temperature for ten days, where upon yellow blocks were obtained.
Difference Fourier maps revealed that the hydroxy substituent of one ethanolamine group is disordered over two sites. The subsequent refinement of their occupancies gave the values of 0.844 (4) and 0.156 (4), respectively. All the H atoms were placed in geometrically calculated positions (C—H = 0.93 - 0.97Å and O—H = 0.82 Å) and allowed to ride on their respective parent atoms, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl).
In the crystal structure, there are solvent accesible voids of 121.0 Å3. These voids may initially have contained solvent, but this has been lost without degradation of the structure. There is no significant residual electron density to suggest the presence of solvent of crystallization.
As part of our ongoing studies of Schiff bases, we reported here the synthesis and crystal structure of the title compound (Fig. 1), a new zinc(II) complex with a bidentate Schiff base ligand derived from the condensation of o-vanillin and ethanolamine.
The coordination around zinc is a distored tetrahedral involving two O and N atoms of the ligands. These bond lengths and angles values are similar to the reported values for related structures (Hokelek et al., 2000, Tatar et al., 1999, Dong et al., 2007).
In the crystal structure, the intermolecular hydrogen bonds of O3—H3···O1i and O3—H3···O2i(symmetry code: (i) x, y - 1, Z) (Fig. 2) and the relatively short intermolecular distances H18a···Cgii of 2.962Å (symmetry code: 0.5 - x, 1/2 + y, Z; Cg is the centroid of the C12—17 ring) indicating the prescence of weak C—H···π interaction, stabilize the crystal packing along with van der Waals forces.
The bond lengths and angles in the title structure are similar to those in related structures (Hokelek et al., 2000; Tatar et al., 1999; Dong, et al., 2007).

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 ongoing studies of Schiff bases, we reported here the synthesis and crystal structure of the title compound (Fig. 1), a new zinc(II) complex with a bidentate Schiff base ligand derived from the condensation of o-vanillin and ethanolamine.
The coordination around zinc is a distored tetrahedral involving two O and N atoms of the ligands. These bond lengths and angles values are similar to the reported values for related structures (Hokelek et al., 2000, Tatar et al., 1999, Dong et al., 2007).
In the crystal structure, the intermolecular hydrogen bonds of O3—H3···O1i and O3—H3···O2i(symmetry code: (i) x, y - 1, Z) (Fig. 2) and the relatively short intermolecular distances H18a···Cgii of 2.962Å (symmetry code: 0.5 - x, 1/2 + y, Z; Cg is the centroid of the C12—17 ring) indicating the prescence of weak C—H···π interaction, stabilize the crystal packing along with van der Waals forces.
