Aniline complexes of ruthenium(II) and ruthenium(III) halides

Abstract
The preparations, i.r. and electronic spectra, and magnetic susceptibilities of the ruthenium(III) complexes A[RuX4-(aniline)2](A = Cs, Me4N, C6H5NH3 or C5H6N, and X = Cl, Br, or I); and of the ruthenium(II) complexes [RuL6]Br2 and RuL4Br2(L = a substituted aniline) are reported. From their spectroscopic properties the compounds containing co-ordinated halide are assigned trans-structures. Values of 10Dq obtained from the spectra of [RuL6]Br2 place substituted anilines between ethylenediamine and water in the spectrochemical series. A compound [C6H5NH3]5[Ru3Br14] has been partly characterised.
