The structures of some of them have also been determined by X\u2010ray crystallography. Electrochemical studies demonstrate the presence of a ligand\u2010centered reduction originating from the cyclometalating C^N ligand, whereas the first oxidation wave is associated with an alkynyl ligand\u2010centered oxidation. The electronic absorption and photoluminescence properties of the complexes have also been investigated. In dichloromethane solution at room temperature, the low\u2010energy absorption bands are assigned as the metal\u2010perturbed \u03c0\u2013\u03c0* intraligand (IL) transition of the cyclometalating C^N ligand, with mixing of charge\u2010transfer character from the aryl ring to the pyridine or isoquinoline moieties of the cyclometalating C^N ligand. The low\u2010energy emission bands of the complexes in fluid solution at room temperature are ascribed to originate from the metal\u2010perturbed \u03c0\u2013\u03c0* IL transition of the cyclometalatng C^N ligand.
