was cleanly hydroborated with HB(C6F5)2 to afford [Fe(η5-C5H4PMes2)(η5-C5H4CH2CH2B(C6F5)2)] (7). Compound 7 adopted an open non-interacting P/B frustrated Lewis pair (FLP) structure in the crystal state as well as in a solution. This frustrated Lewis pair heterolytically cleaved dihydrogen under mild conditions to give the respective zwitterionic [P]H+/[B]H– phosphonium/hydroborate product, [Fe(η5
