Synthesis and photophysical characterization of a bis-pincer osmium complex

A bis-pincer osmium complex Os(PCP)2 (PCP = 2,6-(CH2PPh2)2C6H3, Ph = C6H5) has been prepared in up to 42% yield. The complex is composed of a racemic mixture and shows metal centered emission with a 3% quantum yield in the solid state (298 K).
