Abstract top

The asymmetric unit of the title compound, [Zn(C19H16Cl4N2O2)(H2O)], comprises two crystallographically independent molecules. The geometry around the ZnII atoms is distorted trigonal-bipyramidal, supported by the N2O2 donor atoms of the tetradentate Schiff base and a coordinating water molecule. The dihedral angles between the benzene rings in the two molecules are 34.10 (15) Å and 30.61 (15) Å. In the crystal, neighbouring independent molecules are linked by pairs of O-H...O hydrogen bonds, forming dimers with R22(6) ring motifs, and by O-H...Cl hydrogen bonds. There are short Cl...Cl [3.4728 (16), 3.4863 (16), and 3.388 (1) Å] contacts present, and molecules are also linked by C-H...O and [pi]-[pi] [centroid-centroid distance = 3.671 (2) Å] interactions.

Comment top

Schiff base complexes are one of the most important stereochemical models in transition metal coordination chemistry, with their ease of preparation and structural variations (Granovski et al., 1993; Blower et al., (1998).

The asymmetric unit of the title compound, Fig. 1, comprises two crystallographically independent molecules. The bond lengths (Allen et al., 1987) and angles are within the normal ranges and are comparable to those found for a related structure (Zhong-Lu et al. 2006). The geometry around the ZnII atom is a distorted trigonal-bipyramide which is supported by the N2O2 donor atoms of the coordinated Schiff base and a coordinated water molecule. The dihedral angles between the benzene rings are 34.10 (15) Å [C1-C6/C14-C19] and 30.61 (15) Å [C20-C25/C33-C38].

In the crystal, neighbouring independent molecules are linked by pairs of O—H···O hydrogen bonds forming dimers with R22(6) ring motifs (Bernstein et al., 1995), and by O-H···Cl hydrogen bonds (Table 1 and Fig. 2). Short Cl···Cl [Cl2···Cl6iv = 3.4728 (16)Å, (iv) x-1/2, -y+3/2, z+1/2; Cl4···Cl7v = 3.4863 (16)Å, (v) -x+1/2, y-1/2, -z+3/2; Cl6···Cl8vi = 3.388 (1)Å, (vi) -x+5/2, y-1/2, -z+3/2] contacts are present in the crystal structure (Fig. 3); they are shorter than the sum of the van der Waals radii of Cl atoms [3.50 Å; Bondi, 1964]. The crystal structure is further stabilized C—H···O (Table 1) and π···π interactions [Cg1···Cg2i = 3.671 (2)Å, (i) x-1, y, z; Cg1 and Cg2 are the centroids of the C14–C19 and C20–C25 benzene rings, respectively].

Experimental top

The title compound was synthesized by adding 3,5-dichloro-salicylaldehyde-2,2-dimethyl-1,3- propanediamine (2 mmol) to a solution of Zn(OAc)2. 2H2O (2.1 mmol) in ethanol (30 ml). The mixture was refluxed with stirring for half an hour. The resultant solution was filtered. Light-green single crystals of the title compound, suitable for X-ray structure determination, were recrystallized from ethanol by slow evaporation of the solvents at room temperature over several days.

Refinement top

The H atoms of the water molecules were located in a difference Fourier map and were constrained to ride on the parent O atoms, with Uiso(H) = 1.5Ueq(O). The C-bound H-atoms were included in calculated positions and treated as riding atoms: C-H = 0.93, 0.96 and 0.97 Å for CH, CH3 and CH2 H-atoms, respectively, with Uiso(H) = k × Ueq(parent C-atom), where k = 1.5 for CH3 H-atoms and = 1.2 for other H-atoms.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
