Abstract top

The title tetranuclear SnIV complex, [Sn4(C4H9)8(C10H6NO2)4O2], is a cluster built up by inversion symmetry around the central Sn2O2 ring. The coordination geometries of the Sn atoms involved can be classified into two types: the five-coordinate Sn atoms of the central Sn2O2 core have a trigonal-bipyramidal geometry, with axial positions occupied by a [mu]3-O atom and a [mu]2-O atom belonging to the nonchelating quinaldate ligand. The peripheral Sn atoms are six-coordinate, with a distorted octahedral geometry. The methyl group of an n-butyl ligand is disordered over two sites, with occupancies of 0.643 (12) and 0.357 (12).

Comment top

The title compound, (I), is a cluster containing four Sn atoms (Fig. 1). The whole molecule lies on an inversion center, with a central Sn2O2 core. The structure is similar to that previously characterized with 3-hydroxypyridine-2-carboxylate as main ligand (Tian et al., 2005). The three-coordinated µ3 atom O5 in the Sn2O2 ring is bonded to a Bu2SnO2N unit. Moreover, the C1 carboxylate group coordinates to each independent Sn atom in a bridging mode (Fig. 2). The geometry of the Sn1 atom in the Sn2O2 ring is distorted trigonal-bipyramidal with atoms O1 and O5i [symmetry code (i): -x + 1, -y + 2, -z] in axial positions, while two n-butyl groups and atom O5 form the equatorial plane. For the Sn2 atoms, six primary bonds are formed: three to the O atoms, two to the C atom of n-butyl groups, and one to the chelating quinoline N atom. Thus, the Sn2 centers display a distorted octahedral coordinated geometry. The Sn—O and Sn—N bond lengths (Table 1) are similar to those observed in related organotin carboxylates (Ma et al., 2004).

Experimental top

The reaction was carried out under a nitrogen atmosphere. Quinaldic acid (1 mmol) and sodium ethoxide (1.2 mmol) were dissolved in ethanol (30 ml) in a Schlenk flask and stirred for 0.5 h. Dibutyltin dichloride (1 mmol) was then added and the reaction mixture was stirred for 12 h at 313 K. The resulting clear solution was evaporated under vacuum. The product was crystallized from a mixture of dichloromethane/methanol (1:1). Yield: 83%; m.p. 426 K. Analysis: calculated for C72H96N4O10Sn4: C 52.33, H 5.86, N 3.39%. found: C 52.27, H 5.95, N 3.47%.

Refinement top

Atoms C24 was found to be disordered over two positions (C24 and C24'). Site occupation factors were refined and converged to 0.643 (12) and 0.357 (12) for C24 and C24', respectively. All C—C bonds lengths in n-butyl groups were restrained to 1.53 (2) Å. In n-butyl groups, C atoms closer than 1.7 Å were restrained, with deviation of 0.04 Å2, to have the same Uij components. H atoms were positioned geometrically, with C—H = 0.93, 0.96 and 0.97 Å for aromatic, methyl and methylene H atoms, respectively, and constrained to ride on their parent C atoms, with Uiso(H) = xUeq(carrier C) where x = 1.5 for methyl groups and x = 1.2 otherwise.
