2-pyridine cyclic triimidazole as chelating and bridging ligand in mono- and hexanuclear Re(I) complexes with emissive properties in solution and in the solid state

Two luminescent Re(I) complexes, namely the mononuclear fac-[ReCl(CO) 3 (TT-Py)] (1) and the hexanuclear [{Re(μ-Cl)(CO) 3 (μ-TT-Py)}{Re 2 (μ-Cl) 2 (CO) 6 }] 2 ( 2 ), have been isolated in high yields by one-pot reaction between [ReCl(CO) 5 ] and different amounts of nitrogen...
