In the title complex, [Sn(C4H9)(C17H11N3O2)Cl2]·2CH4O, the Sn atom is in a distorted octahedral geometry, with Sn—O distances of 2.093 (3) and 2.125 (3) Å. The tridentate Schiff base coordinates to the Sn via the azomethine N atom, the hydroxyl O atom and the carbonyl O atom. The complex is stabilized by intramolecular O—H...O hydrogen bonds, forming a one-dimensional chain.
The Landau-Luttinger liquid formulation is used to investigate the physics of the one-dimensional Hubbard model in a magnetic field of arbitrary strength H. The low lying charge and spin excitations are studied. A novel branch of sound wave-like spin excitations arises for H>0. The low temperature thermodynamics is considered in some detail.
