Abstract

A para-substituted triphenylphosphine oxide with terminal vanadocene centers has been prepared and is, to our knowledge, the first example of an untethered C_3v-symmetric triarylphosphine oxide in the solid state. Crystallographic and DFT studies suggest this locked conformation is due to intermolecular H-bonding interactions. Electrochemical measurements suggest these interactions may persist in solution. A monometallic variant, adopting the standard C₃ propeller geometry, has also been synthesized for comparison.
