Popis:	The reaction of ruthenium(III) perchlorate with some polytertiary phosphines or arsines has been investigated. With bidentate ligands in ethanol cationic complexes of the type [Ru(L–L)3(ClO4)]ClO4(L–L = Ph2PCH2PPh2, Ph2PCH2CH2PPh2, Ph2AsCH2CH2AsPh2, or Ph2AsCH2CH2PPh2) are obtained. With terdentate ligands the complexes obtained are of the type [RuL2(ClO4)][ClO4]2[L = NH(CH2CH2PPh2)2 or NH(CH2CH2AsPh2)2]. The reaction of the complex [RuCl3(AsPh3)2(MeOH)] with AsPh3 and PPh3 in the presence of an excess of NaClO4 in methanol gave [Ru(AsPh3)4(ClO4)2]ClO4 and [Ru(AsPh3)(PPh3)3(ClO4)2]ClO4 respectively. With terdentate ligands [RuCl3(AsPh3)2(MeOH)] afforded mixed-ligand cationic complexes of the type [Ru(AsPh3)2L(ClO4)][ClO4]2[L = NH(CH2CH2PPh2)2 or NH(CH2C2AsPh2)2]. Perchlorate co-ordination is discussed in terms of the i.r. spectra of complexes, and structures are proposed based on the 1H, 31P, and 14N n.m.r. spectra.
