A series of clusters of the form [Et₄N][Fe₂(CO)₆(μ₃-As)}(μ₃-EFe(CO)₄)], where E is either P or As, were synthesized from [Et₄N]₂[HAs{Fe(CO)₄}₃] and ECl₃. AsCl₃ gives the As-only compound; PCl₃ produces compounds having two As atoms with one P atom, or one As atom and two P atoms, and they can exist as two possible isomers, one of which is chiral. The As₂P and AsP₂ clusters cocrystallize, and their structure as determined by single-crystal X-ray diffraction is given along with the structure of the As-only cluster. Analytical data as well as density functional theory calculations support the formation and geometries of the new molecules.
