1.* (1997 F 5) A. Indicate the oxidation state, d-electron count, and number of unpaired electrons in each of the following isostructural complexes: K4[Fe(CN) 6] and [Et4N]4[V(CN) 6]. Fe2+, d6, 0 unpaired electrons; V2+, d3, 3 unpaired electrons. B. How many unpaired electrons, if any, are in each of the following complexes? Indicate whether either complex would be an oxidizing or a reducing agent. The Co complex has Co in the +2 oxidation state. With 7 d-electrons, it has 1 or 3 unpaired electrons depending on whether the compound is low or high spin. As a 19 electron complex, it will be an electron donor, or a reducing agent. The Fe cation has Fe in the +3 oxidation state. With 5 d-electrons, it has 1 or 5 unpaired electrons depending on whether the compound is low or high spin. As a 17 electron complex, it will be an electron acceptor, or oxidizing agent. |
