Structures, Thermal Properties, and Reactivities of Cationic Rh-cod Complexes in Solid State (cod = 1,5-Cyclooctadiene).

ABSTRACT: Cationic rhodium complexes with 1,5-cyclooctadiene (cod) ligands are important organometallic compounds that are useful as precatalysts; however, their solid-state structures and thermal properties have not been adequately investigated. In this study, we synthesized [Rh(cod)L]X (L = cod, C₆H₆, PhMe; X = SbF₆, (FSO₂)₂N (= FSA), CF₃BF₃, CB₁₁H₁₂) and investigated their phase behaviors, crystal structures, and reactivities. The phase transitions of these salts result in disordered solid-state structures. Moreover, the structural disorder increases with a decrease in the cation symmetry in the SbF₆ salts; [Rh(cod)(PhMe)]SbF₆ exhibits a rotator phase, and the cations in other
