Chloridotris(4-chlorobenzyl-[kappa]C)(triphenylarsine oxide-[kappa]O)tin(IV)

N. H. Johari, K. M. Lo and S. W. Ng

Abstract top

The SnIV atom in the title compound, [Sn(C7H6Cl)3Cl(C18H15AsO)], shows a distorted C3ClOSn trigonal bipyramidal coordination; the axial O-Sn-Cl angle is 170.22 (4)°.

Related literature top

For the synthesis of tri(4-chlorobenzyl)tin chloride, see: Sisido et al. (1961). Triphenylarsine oxide affords a small number of adducts with triorganotin(IV) Lewis acids; see: Lo et al. (2000); Nardelli et al. (1977); Ng & Kumar Das (1993).

Experimental top

Tri(4-chlorobenzyl)tin chloride (0.5 g, 0.93 mmol) and triphenylarsine oxide (0.3 g, 0.93 mmol) were dissolved in chloroform (50 ml). Slow evaporation of the solvent gave large, well-formed colorless crystals.

Refinement top

Hydrogen atoms were placed at calculated positions (C–H 0.95–0.99 Å) and were treated as riding on their parent atoms with U(H) set to 1.2Ueq(C). The final difference Fourier map had a large peak/deep hole in the vicinity of the Sn1 atom.
