The crystal structure of the title salt, [Sn(C₇H₇)₃(C₁₈H₁₅AsO)₂][B(C₆H₅)₄], consists of discrete cations and anions; the tin atom of the cation is five-coordinated in a distorted trans-C₃SnO₂ trigonal-bipyramidal geometry [summation of C–Sn–C angles 360.0 (3)° and O–Sn–O angle 173.1 (1)°]. The structure contains voids of 113 (19) Å³, but no solvent molecule could reasonably be located there.

Comment top

A suggestion for improving the aqueous solubility of triorganotin(IV) compounds, R₃SnX, involves exchanging the X residue by the non-nucleophilic tetraphenylborate anion to generate a salt. However, to prevent aggregation into an oligopolymer, the triorganotin species itself must be stabilized by coordination by two neutral ligands. Of the number of such compounds synthesized, the crystal structure of only one, namely, [(p-ClC₆H₄)Ph₂Sn(Ph₃AsO)₂][BPh₄], has been reported (Ng et al., 1989). The compound exists as non-interacting cations and anions; the tin atom of the cation is five-coordinate in a trans-C₃SnO₂ trigonal bipyramidal geometry. The title tribenzyltin adduct (Scheme I, Figs. 1 & 2) is a similar non-interacting salt. The trans angle at tin is nearly linear, and the Sn–O–As skeleton is also nearly linear (Table 1).

Experimental top

Tribenzyltin chloride (0.21 g, 0.5 mmol), triphenylarsine oxide (0.32 g, 1 mmol) and sodium tetraphenylborate (0.17 g, 0.5 mmol) were dissolved in ethanol (100 ml). The solution was heated for an hour. Then the mixture was filtered and the filtrate evaporated at room temperature to obtain the colorless crystals.
