Abstract

We report the synthesis and characterization of two new rhenium(I) complexes [ReBr(CO)3(L)] (1) and [Re(CO)3(L)(m-XylylNC)]OTf (2), where m-XylylNC is 2,6-dimethylphenylisocyanide. These compounds are derived from the dipyrido[3,2-a:2′,3′-c]phenazine ligand functionalized with borneol group at the second position (m-XylylNC = 2,6-dimethylphenyl isocyanide). As determined by single crystal X-ray diffraction, the molecular structure of the 2 cation has a distorted octahedral geometry at the rhenium center coordinated by N,N′-chelating ligand L, one isonitryl and three carbonyl ligands.
