Dibut­yl{N′-[1-(5-chloro-2-oxidophenyl-κO)ethyl­idene]-3-hy­droxy-2-naphtho­hydrazidato-κ² N′,O ²}tin(IV)

Abstract

The five-coordinate Sn^IV atoms in the two crystallographically independent mol­ecules of the title compound, [Sn(C₄H₉)₂(C₁₉H₁₃ClN₂O₃)], are in distorted cis-C₂NO₂Sn trigonal-bipyramidal coordination environments. The tridentate dianion of the Schiff base, N′-[1-(5-chloro-2-oxidophen­yl)ethyl­idene]-3-hy­droxy-2-naphtho­hydrazide, displays inter­molecular O—H⋯N hydrogen bonding, which stabilizes the overall compound.

Comment

Schiff bases derived from substituted salicylaldehydes have been widely used as polydentate ligands in the preparation of metal complexes. The metal complexes of these hydrazones with substituted salicylaldehydes are known to possess potential biological activities such as antifungal, anticancer and many others [Bernhardt et al. (2006), Ainscough et al. (1999), Mohd Ali et al. (2004)]. We have earlier reported the synthesis and molecular structure of a diphenyltin complex of the Schiff base derived from the reaction of 3-hydroxy-2-naphthoic hydrazide with 5-chlorobenzaldehyde [Lee et al. (2009)]. The crystal structure of this complex consists of discrete molecules in which the tin atom is O,N, O'-chelated by the deprotonated Schiff base ligand. As an extension of our work in structural characterization of organotin with hydrazones, we report here the molecular structure of a dibutyltin complex of a Schiff base derived from the reaction of 3-hydroxy-2-naphthoic hydrazide with 5-chloro-2-hydroxyacetophenone. The unit cell of the title complex consists of two crystallographically independent molecules. In both molecules, the Schiff base ligand, N'-[1-(5-chloro-2-oxidophenyl)ethylidene-3-hydroxy-2-naphthohydrazone] forms a tridentate dianion which coordinated to the dibutyltin fragment in a distorted cis-C₂NO₂Sn trigonal bipyramidal configuration; the axial O—Sn—O angle are 153.03 (13)^o and 152.41 (13)^o.

Experimental

The Schiff base ligand was prepared by the condensation reaction of 3-hydroxy-2-naphthoic hydrazide with 5-chloro-2-hydroxyacetophenone. The prepared Schiff base (0.74 g, 2.0 mmol), dibutyltin dichloride (0.61 g, 2 mmol) and triethylamine (0.6 ml) were refluxed in 50 ml of ethanol for 5 h. The solution was left for crystallizaton at room temperature during which yellow crystals were obtained.

Refinement

Hydrogen atoms were placed at calculated positions (C–H 0.95 to 0.98 Å) and were treated as riding on their parent carbon atoms, with U(H) set to 1.2–1.5 times U_eq(C). The hydroxy-H was refined with a restraint of 0.84 ± 0.01 Å.

Special details

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 takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused 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 andgoodness of fit S are based on F2, conventional R-factors R are basedon F, with F set to zero for negative F2. The threshold expression ofF2 > σ(F2) is used only for calculating R-factors(gt) etc. and isnot relevant to the choice of reflections for refinement. R-factors basedon F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
