Squeezing Bi: PNP and P2N3 Pincer Complexes of Bismuth(III

Abstract

We report the first application of a rigid <i>P<sub>2</sub>N<sub>3</sub></i> pincer ligand in p-block chemistry by preparing its bismuth complex. We also report the first example of bismuth complexes featuring a flexible <i>PNP</i> pincer ligand, which shows phase-dependent structural dynamics. Highly electrophilic, albeit thermally unstable, Bi(III) complexes of the <i>PNP</i> ligand were also prepared. <br>
