However, in view of the sensitivity of both ΔH and ΔS to the chosen values for the limiting high- and lowspin magnetic moments, it is appropriate to use more conservative error limits for the derived values, as has been done in the main text. Measured and calculated moments and a least-squares fit are available as Supporting Information.

Spin relaxation traces recorded for the complex in Nafion 117 membrane as a host matrix displayed clear evidence of thermally-activated behavior over the temperature interval 170-77 K, with relaxation limes ranging from 137 ns at 170 K to 3.4 μs at 77 K. This aspect is still being investigated and the findings will he reported elsewhere.
