Summary: | In the solvated title salt, [RhCl2(C5H5N)4]Cl·4CH3OH, the RhIII atom lies on a special position of 2.22 site symmetry. Consequently, the cationic complex has molecular D2 symmetry with a trans disposition for two equivalent Cl− and four equivalent pyridine ligands. The Rh—Cl and Rh—N bond lengths are 2.3452 (7) and 2.064 (2) Å, respectively. The planes of the coordinating pyridine ligands are tilted synchronously, with a dihedral angle of 40.76 (9)° between the least-squares pyridine plane and the coordination plane defined by the RhIII and four pyridine N atoms. The chloride counter-anion is located on a crystallographic \overline{4}.. site, and is surrounded by four methanol molecules to which it is bound in a pseudo-tetrahedral arrangement by O—H...Cl hydrogen bonds.
