Sumario:Preparation, characterization and structural properties of a novel bis-phosphaalkenyl based PNP-pincer are reported. In this pincer the π-system is delocalized over all three donor sites, which was demonstrated with DFT calculations, UV–Vis measurements and structural findings. As a consequence of this extended delocalization the π-system reveals near coplanarity which is evident from the first crystal structure for an uncomplexed bisphosphaalkenyl PNP-pincer.
