[N'-(5-Bromo-2-oxidobenzylidene-[kappa]O)-3-hydroxy-2-naphthohydrazidato-[kappa]2N',O]dimethyltin(IV)

Abstract top

The SnIV atom in the title compound, [Sn(CH3)2(C18H11BrN2O3)], shows a distorted cis-C2NO2Sn trigonal-bipyramidal coordination geometry, with an axial O-Sn-O angle of 155.27 (9)°. The presence of an intramolecular O-H...N hydrogen bond between the amido N atom and hydroxy H atom in the Schiff base ligand helps to stabilize the overall molecular structure.

Experimental top

The Schiff base ligand was prepared by the condensation reaction of 3-hydroxy-2-naphthoyl hydrazide with 5-bromosalicylaldehyde. The title compound was prepared by refluxing the Schiff base (0.74 g, 2.0 mmol) with dimethyltin oxide (0.32 g, 2.0 mmol) in toluene for 6 h. The solution was filtered and left for recrystallization for a week during which yellow crystals were obtained.

Refinement top

All H-atoms were positioned geometrically and refined using a riding model with d(C-H) = 0.95Å, Uiso=1.2Ueq (C) for aromatic 0.98Å, Uiso = 1.5Ueq (C) for CH3 atoms and 0.84Å, Uiso = 1.5Ueq (O) for the OH group.

Special details top

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.
