posted on 10.12.2019, 19:10 authored by Sok-Yong Cho, Tomoyuki MochidaAlthough the coordination chemistry of rhenium complexes
is a rapidly expanding research field, little is known about their
thermal properties. In this study, we synthesized several rhenium
tricarbonyl complexes with tridentate ligands (L) having
S or N as donor atoms, fac-[Re(CO)3L]X (X = Tf2N [= bis(trifluoromethanesulfonyl)amide)],
PF6) and fac-[Re(CO)3LCl], and investigated their thermal properties and crystal
structures. The Tf2N salts were room temperature ionic
liquids. The S-coordinated complexes, having longer coordination bonds,
were less thermally stable than the N-coordinated complexes. Even
though fac-[Re(CO)3LCl] are
bidentate coordination complexes, they were thermally more stable
than the isomeric tridentate complexes fac-[Re(CO)3L]Cl.
