Chemical conversions of rhodium selenochloride Rh2Se9Cl6
摘要:
Rhodium selenochloride Rh2Se9Cl6 (1) reacts with aqueous solutions of KCN and CsCl and 4-cyanopyridine (4-CNPy) to give complexes KCs2Rh(CN)(6) (2) and RhCl3(4-CNPy)(3) (3). According to X-ray diffraction data, 2 and 3 have mononuclear structures in which the rhodium atoms are in the oxidation state III and six-coordinate environment. Reactions 1 with CN-containing ligands lead to complete displacement of selenium-containing ligands from the rhodium coordination sphere.
