2-(Ethoxycarbonyl)quinolinium butyltrichlorido(quinoline-2-carboxylato-κ2N,O)stannate(IV)

In the title compound, (C12H12NO2)[Sn(C4H9)(C10H6NO2)Cl3], the Sn atom is coordinated by one O and one N atom of a quinolinium-2-carboxylate anion, three Cl atoms and one butyl ligand within a distorted octahedron. Three C atoms of the butyl ligand are disordered and were refined using a split model; the site occupancies are 0.57 and 0.43. The NH group of the cation is involved in intermolecular N—H...O hydrogen bonding.
