respectively. In the latter two complexes the OsN moiety is perpendicular to the plane of the chelating ligand. The spectroscopic, photophysical and photochemical properties of the newly prepared complexes have been studied. All have long-lived and emissive 3[dxy′,dπ.] excited states in the solid state and in fluid solution at room temperature. The complex mer-[Os(terpy)NCl2][ClO4] has the longest emission
