The investigation into the substitution and addition chemistry of Re(σ2-terpy)(CO)3Cl shows that the chloride in Re(σ2-terpy)(CO)3Cl (1) may be substituted for acetonitrile to give [Re(σ2-terpy)(CO)3(CH3CN)][PF6] (2), but in the cationic complex [Re(σ2-terpyMe)(CO)3Cl][PF6] (4), where the pendant pyridine has been methylated, substitution of the chloride could not be achieved using standard conditions. However, use of [Re(σ2-terpyMe)(CO)3I][PF6] (3) results in the formation of [Re(σ2-terpyMe)(CO)3(CH3CN)][PF6]2 (5). The acetonitrile ligand in complex 2 was found to be labile and could be substituted by pyridine donors.
