The synthesis and characterization for a series of meridionally-coordinated terpyridine rhenium(I) dicarbonyl complexes from mer,cis-Re(tpy-κ3N)(CO)2Cl, 2, are described. Reaction of the mer,cis-Re(tpy-κ3N)(CO)2Cl via halide extraction in acetonitrile produced the complex mer,cis-[Re(tpy-κ3N)(CO)2(NCCH3)]+, 3. Complex 3 was found to undergo thermal substitution to produce mer,cis-[Re(tpy-κ3N)(CO)2(L)]+ (where L = PPh3 (4), NC5H5 (5), and PEt3 (6)). The spectroscopic and structural characterizations are discussed.
Preparative route for mer,cis-[Re(tpy-κ3N)(CO)2(L)]+ (where L = PPh3, NC5H5, and PEt3) complexes from mer,cis-Re(tpy-κ3N)(CO)2Cl. [Display omitted]
