The l-leucinium cations in the title compound adopt extended conformations that maximize the separation between the methyl groups [–CH(CH3)2] and the polar NH3+ and COOH groups.
The title compound, (C6H14NO2)2[SnCl6]·2H2O, features l-leucinium cations adopting extended conformations, which maximizes the separation between the methyl groups [–CH(CH3)2] and the polar NH3+ and COOH moieties. Additionally, an intramolecular hydrogen bond between the ammonium (NH3+) group and the carboxyl group induces a slight reduction in the C—C—N bond angles, with an average value of 106.5°, compared to the ideal tetrahedral angle of 109.5°. The NH3+ group is nearly coplanar with the C—C—C—C carbon chain in both fragments, whereas the carboxyl (COOH) group and the methyl group at the C5 position deviate significantly from this plane. The octahedral complex anion is close to regular. In the crystal, an extensive network of hydrogen bonds links the components into a three-dimensional network.
