abstract = {The reactions of K5Pn4 (Pn = Sb and Bi) and CpRh(PPh3)2 (Cp = C5H5, cyclopentadiene) in ethylenediamine (en) solutions resulted in a series of new Pn73− adducts, {Pn8[Rh(PPh3)]2}2−, {Sb7[Rh(PPh3)]2}2−, and {Sb7[Rh(PPh3)]3}2−, through slight variations in reaction conditions. These clusters represent rare electron-deficient group 15 polyhedral clusters comprising Pn73− with RhPPh3 units in an η5 coordination mode. Notably, the anionic clusters {Sb8[Rh(PPh3)]2}2−, {Sb7[Rh(PPh3)]2}2−, and {Sb7[Rh(PPh3)]3}2− are the first Rh-Sb binary Zintl clusters to date. The synthesis, structure, and bonding of these new deltahedral hybrids were studied for the first time, revealing a highly versatile chemistry associated with classical Pn73− cages and offering a pathway to prepare polyhedral hybrid clusters based on Pn73− cages.}
