What is it about?
Gamma-irradiated single crystals of [N(PPh3)2][W(CO)4H{P(OMe)3}] contain an anisotropic EPR signal which exhibits hyperfine coupling to a single 31P nucleus. We used aligned crystals and single crystal EPR to examine back-bonding in such organometallic radicals.

Why is it important?
Comparison with other 31P hyperfine measurements suggests that EPR provides a good indication of the efficiency of back-bonding in such organometallic radicals.
