voltammetry complex 2 shows two two-electronic reduction processes, at −0.98 and −1.56 V. Electrochemical or chemical reduction of 2 under carbon monoxide give compound 3. Crystal structure of 3 was solved in the P21/n space group, Z = 2, with cell parameters a 9.394(2), b 17.194(4), c 10.948(2) Å, and β 111.62(2)°. The structure consists of a rhodium atom in a square planar environment with the two chlorine
