Thomas Rauchfuss Justice, Aaron 2015-09-25T22:13:51Z 2015-09-25T22:13:51Z 10000-01-01 2008 2008 The unsaturated character of [1(CO)3(PMe 3)]+ is indicated by its reactivity with CO, which occurs in seconds. The product; [Fe2(S2C2H 4)(mu-CO)(CO)3(PMe3)(dppv)]+ [1(CO)4(PMe3)]+ is highly unstable and could only be observed under a CO atmosphere. The EPR spectrum for [1(CO)4(PMe3)]+ featured a doublet of triplets, coupled to three phosphorus nuclei with two distinct phosphorus hyperfine couplings (A(31P) = 283, 32 and 34 MHz). Based upon the changes in the EPR, upon binding CO the unpaired spin becomes delocalized over both iron centers resulting in two Fe(1.5) metal centers.
