    • The other series are not unambiguously complete in the same way and therefore cannot be used for comparison of different members of an isostructural series. For the Os-Ln series, only Os-Gd could be structurally characterized; the other members did not form single crystals, possibly because they are of a different structural type. For the Os-Ln-Bpym series, only two members of structural type A and three of type B could be isolated as analytically pure crystalline solids (see the Experimental Section, The structures of the members of the Os-Ln-PhenB series (Figure 4) contain some [Os(phen)(CN)4]2- units that are connected to Ln(III) centers and some that are not. This leads to different degrees of quenching for different Os(II) units in the same crystal, considerably complicating any photophysical analysis based on measuring residual Os(II)-based emission in the presence of different Ln(III) ions. The Os-Ln-PhenA s

This leads to different degrees of quenching for different Os(II) units in the same crystal, considerably complicating any photophysical analysis based on measuring residual Os(II)-based emission in the presence of different Ln(III) ions. The Os-Ln-PhenA series is (i) complete, (ii) isostructural, and (iii) devoid of "free" Os(II) units that are not connected to Ln(III) centers; thus, it is an ideal basis for a systematic comparison of photophysical properties.
