Preparations of [Rh(Hdmg)2(H2O)2]ClO4 (1) (Hdmg = dimethylgyoximate) from [Rh(H2O)6] (ClO4)3 and dimethylglyoxime and of [Rh(Hdmg)2(PPh3)2]ClO4 (2) from 1 and PPh3 are described. 1 crystallizes in the C2/c space group with a = 14.910(3), b = 6.058(1), c= 18.617(4) A, β = 107.649(8)°, Z=4. The structure was refined up to R = 0.021 for 1849 reflections. The IR and NMR spectra and electrochemical behavior of 1 and 2 are discussed and compared with other rhodoximes. Three polarographic and CV processes can be detected for 2, the first two, respectively to Rh(II) and Rh(I), being followed by fast reactions.
