2-(Methoxycarbonyl)quinolinium tetrachlorido(quinoline-2-carboxylato-κ²N,O)stannate(IV) methanol solvate

In the title salt, (C₁₁H₁₀NO₂)[SnCl₄(C₁₀H₆NO₂)]·CH₃OH, the Sn atom is chelated by the quinolincarboxylate unit and it exists in a distorted octahedral coordination geometry. The cation is linked to the solvent molecule by an N—H

O hydrogen bond; the solvent molecule is linked to the anion by an O—H

O hydrogen bond.

Comment top

Quinolin-2-carboxylic acid forms a number of compounds with organotin(IV) systems in which the deprotonated anion N,O-chelates to the tin atom. Such organotin carboxylates are conveniently synthesized by the reaction of an organotin chloride with the sodium salt of the carboxylic acid. Curiously, the reaction of sodium quinolin-2-carboxylate with n-butyltin trichloride furnishes the n-butyltrichlorido(quinolincarboxylato)stannate anion, whose charge is balanced by an ethyl quinoliniumcarboxylate cation (Wang et al., 2008). The ethyl unit arises from the ethanol solvent used in the synthesis.

In our hands, the reaction of quinolin-2-carboxylic acid with stannic chloride has yielded a similar salt, which crystallizes as a methanol solvate (Scheme I, Fig. 1). The solvent is also involved in the esterification of the acid to furnish the cation. The cation is linked to the solvent molecule by an N–H···O hydrogen bond; the solvent molecule is linked to the anion by an O–H···O hydrogen bond.

Experimental top

Stannic chloride pentahydrate (1 mmol, 0.350 g) and quinaldic acid (2 mmol, 0.173 g) were dissolved in dry methanol. The solvent was allowed to evaporate to afford colorless crystals after 1 week.
