Abstract

A simple synthetic procedure (reaction between Re(CO)5Cl and 8-hydroxyquinoline, HOX, in boiling toluene) leads to the dimeric complex Re2(CO)6(OX)2. In coordinating solvents Re2(CO)6(OX)2 undergoes dissociative solvolysis (via a second order reaction) to form monomeric species of general formula Re(CO)3(OX)solv. In non-coordinating media, however, the dimeric complex remains unaffected. Molecular structures of both forms (which are in accord with IR absorption spectra) were confirmed by means of X-ray measurements. UV-VIS spectroscopic (absorption and emission) properties of both newly synthesized Re(I) complexes have been investigated and the differences in their luminescence properties have been briefly discussed.
