Comment top

In the structure of the title compound, (I), (Fig. 1) the Sn1 atom is in a distored trigonal-bipyramidal coordination formed by a tridentate ligand of the azomethine N atom, the hydroxyl O atom and the carbonyl O atom (Table 1). The dihedral angles between the two chelated benzene rings: O2—Sn1—N2 and O3—Sn1—N2 are 83.30 (9) and 71.73 (9)°, respectively. The Sn atom is coordinated in distorted trigonal-bipyramidal arrangement with O2 and O3 located in the axial positions [O2—Sn1—O3 = 155.02 (9)°] and the C15, C16 and N2 in the equatorial positions. The sum of the C15—Sn1—C16 [146.08 (14)], C15—Sn1—N2 [106.13 (11)] and C16—Sn1—N2 [107.23 (11)°] bond angles is 359.44°, indicating approximate co-planarity for these atoms. Comparing the length of CN 1.270Å and C—N 1.470 Å, both bonds, C8—N2 (1.287 (4) Å) and C9—N1 (1.304 (4) Å) should be CN. The N1—N2 bond (1.400 (3) Å) is a single-bond (Yang et al., 1999). The Sn1—N2 distance is close to the sum of the covalent radii of 2.15Å (Sanderson, 1967), indicating a strong Sn—N interaction. Very similar structural parameters were observed in the compound studied by Yearwood et al. (2002).

Experimental top

A mixture of dimethyltin oxide (0.3295 g, 2.0 mmol) and 3-methoxy-2-oxideobenzaldehyde(3-pyridyl)methyl-hydrazone (0.5420 g, 2.0 mmol) in methanol (50 ml) was heated under reflux for 6 h. The obtained clear solution was evaporated under vacuum. The product was crystallized from a mixture of dichloromethane/ethanol (1:1) to yield blocks of (I). Yield 0.5936 g, 71%, m.p. 453 K, analysis, calculated for C₁₆H₁₇N₃O₃Sn: C 45.97, H, 4.10; N 10.06%; found: C 46.02, H 4.05, N, 10.09%.

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.
