[Cr(CO)4(tmp)] is elctrochemically ixidized to the corresponding cation vhich was characterized by EPR, IR, and UV-Vis spectroelectrochemistry at 193 K and by DFT calculations. It is a low-spin d5 Cr(I) complex. Oxidation is a accompanied by a large shift of electron density towards the Cr atom, manifested by a by nearly 100 cm-1 upward shift of the n(CO) IR bands. Spin density is lokalized mostly on the Cr atom but the charge on Cr is nearly the same both in the neutral and cationic complexes.
