occupying the apical positions. The absorption spectra of complexes [1]+ and [2]+ display structured d–d bands between 400 and 550 nm, a feature that is absent in the d–d absorption of the Co(III) complexes [3]+–[6]+. Contrasting emission behaviors were observed: the Cr(III) complexes display metal-centered phosphorescence, while the Co(III) species exhibit ligand-based fluorescence. Time-delayed phosphorescence
