Abstract

Reaction of the water-soluble phosphine phosphonic acid p-TPPTP(H)s (p-triphenylphosphine triphosphonic acid) with Co₂(CO)₈ under biphasic conditions results in the formation of Co₆(CO) ₃(p-TPPTP)₂(H₂O)₂₄·24H ₂O (2) or Co₄(CO)₃(p-TPPTP)₂(H ₂O)₂₄·24H₂O (3) depending on the pH of the solution. These supramolecular organometallic Co(I)/Co(II) complexes contain either six (2) or four (3) crystallographically distinct cobalt ions. The cation [Co(CO)₃(p-TPPTP)₂]⁺ from 2 was reacted with titanium tetraisopropoxide via a sol-gel method to give a titania-supported Co(I) olefin hydroformylation catalyst, which was characterized using solid-state ³¹P NMR, IR, and XPS.
