Abstract

By introducing [Pd(PPh3)4] into a P73− solution, we have successfully synthesized and crystallized [Pd2(η4-P7)2]4− (1a) in [Na(crypt-222)]41a. As a phosphide congener of the reported [Pd2As14]4−, 1a can be viewed as a Pd2 sandwiched by two (η4-P7) units, representing the first organic-ligand–free Pd–P cluster. In addition, 1a provides a platform for investigating Pd–P alloys on the molecular level.
