New ruthenium(III) complexes of the type [RuX2en2] A(en = ethylenediamine, X2 = C2O4, Cl H 2O, Cl l, Cl2, Br2, or l2; A = Cl, Br, l, ClO4, or p-Me·C6H4·SO 2·O) have been isolated, together with complexes of the related ligands triethylenetramine and optically active propylenediamine. Magnetic susceptibilities show that all the compounds have the spin-paired d5 configuration. The cation [RuCl2en2] + has been resolved into its optical enantiomorphs, and its structure related to that of other bis(ethylenediamine)ruthenium(III) compounds, all of which are assigned a cis configuration. Ultraviolet, visible, and infrared spectra are reported, and the use of infrared spectra in the detection of geometrical isomerism is discussed. New mono-ethylenediamine complexes [RuX 4en]- have been isolated in combination with the cations [RuX2en2]+ and (phen H)+ (phen = 1,10-phenanthroline; X = Cl, Br, l, or 1/2;C2O4).
