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 intra-molecular 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 tetra-hedral 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 octa-hedral complex anion is close to regular. In the crystal, an extensive network of hydrogen bonds links the components into a three-dimensional network.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
