A dipyrrin complex has been one of the most utilized fluorescent dyes, and a variety of dipyrrin complexes show intriguing functions based on the various coordination structures of the central element. We now report the synthesis, structure, and photophysical properties of germanium and stannane complexes of the N2O2-type tetradentate dipyrrin, L center dot Ge and L center dot Sn, which are heavier analogues of the previously reported dipyrrin silicon complex, L center dot Si. The central group-14 atoms of the monomeric complexes have geometries close to trigonal bipyramidal (TBP), in which the contribution of the square-pyramidal (SP) character becomes higher as the central atom is heavier. Interestingly, L center dot Sn formed a dimeric structure in the crystal. All complexes L center dot Si, L center dot Ge, and L center dot Sn showed a fluorescence in the red/NIR region. Fluorescence quantum yields of L center dot Ge and L center dot Sn are higher than that of L center dot Si. These results indicated that the central atom on the dipyrrin complexes contributes not only to the geometry difference but also to tuning the fluorescence properties.
