Abstract

The fac-Re(OH₂)₃(CO)₃⁺ moiety was investigated with a known bidentate ligand, acetylactone (acac) and amine based ligands in a 2 + 1 and tridentate approach. In the 2 + 1 approach, the fac-Re(CO)₃(acac)(OH₂) was reacted with ethylamine to yield the monomer version fac-Re(CO)₃(acac)(NH₂Et), 1. Based on the Schiff base condensation of a ketone and a primary amine, a tridentate ligand approach for fac-Re(OH₂)₃(CO) ₃⁺ utilizing the reactivity of acac and diamine ligands (1,2 ethylene, 1,3 propylene, 1,4 butylene) was explored in a didactic manner: 1) an in situ ligand synthesis approach reacting fac-Re(CO)₃(acac) (OH₂) with the diamine (2 + 2 = 3) or 2) direct complexation of fac-Re(OH₂)₃(CO)₃⁺ with the prepared ligand. The results observed with rhenium complexes were characterized by standard chemical analysis and X-ray analysis.
