•Mixed-donor platinum pincer complexes can be prepared via cyclometalation.•The observed reactions provide insights into the mechanism of cyclometalation.•Pt(POCN)Br is luminescent.
We report the synthesis of the novel pincer complex κP,κC,κN-[2,6-(iPr2PO)-(C6H3)(CH2[c-N(CH2)4O])]PtBr (Pt(POCN)Br, 1a) by direct cyclometalation of PtBr2(SEt2)2. This represents the first report of a mixed-donor platinum pincer complex synthesized using cyclometalation. The complex is emissive in the solid state and frozen solution. Comparison of the structure of 1a to related pincer complexes provides insights into the effect of pincer arm donor substituents on cyclometalation.
Graphical abstractSynthesis of a luminescent platinum POCN pincer complex by cyclometalation is reported. The first platinum POCN pincer complex to be prepared by this route provides insights into the cyclometalation process.Figure optionsDownload full-size imageDownload as PowerPoint slide
