The asymmetric unit of the title compound, [Co(C₂₃H₂₈N₂O₄)(C₉H₉O₃)]·C₂H₅OH·H₂O, comprises one complex molecule, a water molecule of crystallization and an ethanol molecule of crystallization, which is disordered over two positions with a ratio of refined site occupancies of 0.567 (10):0.433 (10). The Co^III ion is in a slightly distorted octahedral geometry involving an N₂O₂ atom set of the tetradenate Schiff base ligand and two O atoms of 2-ethoxy-6-formylphenolate. The H atoms of the water molecule act as donors in the formation of bifurcated intermolecular O—H

(O,O) hydrogen bonds with the O atoms of the hydroxy and ethoxy groups with R₁²(5) ring motifs, which may influence the molecular conformation. The crystal structure is further stabilized by intermolecular O—H

O and C—H

O interactions.

Comment top

Schiff base complexes are one of the most important stereochemical models in transition metal coordination chemistry, with the ease of preparation and structural variations (Granovski et al., 1993). Metal derivatives of the Schiff bases have been studied extensively, and they play a major role in both synthetic and structurel research (Elmali et al., 2000; Blower et al., 1998). The structure of the title compound was determined to clarify the identity of the synthesis product.

The asymmetric unit of the title compound, Fig. 1, [Co(C₃₂H₃₇N₂O₇)]. C₂H₆O. H₂O, comprises a unit of the complex, a water molecule of crystallization and an ethanol of crystallization. The H atoms of the water molecule act as donors in the formation of bifurcated O—H···(O,O) intermolecular hydrogen bonds with the O atoms of the hydroxy and ethoxy groups with R²₁(5) ring motifs (Bernstein et al., 1995) which may influence the molecular conformation. The crystal structure is further stabilized by the intermolecular C—H···O and O—H···O interactions (Table 1).

Experimental top

The title compound was synthesized by adding 6,6'-Diethoxy-2,2'- [2,3-dimethyl-propylenebis(nitrilomethylidyne)]-diphenol (2 mmol) to a solution of CoCl₂. 6 H₂O (2 mmol) in ethanol (30 ml). The mixture was refluxed with stirring for half an hour. The resultant red solution was filtered. Brown 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.

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.
