Mixed ligand triangulotriruthenium cluster carbonyls, Ru3(CO)9(μ-Ph2AsCH2AsPh 2)(L) (L = PPh3, PCy2Ph, P(OCH3)3) and RU3(CO)8(μ-Ph2AsCH2AsPh 2)(μ-Ph2PCH2PPh2) were synthesised and characterised by microanalysis, IR, 1H, 13C and 31P NMR spectrometry. Single crystal X-ray structure determination of Ru3(CO)9(μ-Ph2AsCH2AsPh 2)(PCy2Ph) and Ru3(CO)8(μ-Ph2AsCH2AsPh 2)(μ-Ph2PCH2PPh2) are reported. In both the clusters, the triruthenium framework is planar. In Ru3(CO)9(μ-Ph2AsCH2AsPh 2) (PCy2Ph), the monodentate phosphine occupies an equatorial position for steric reasons. The effect of tri-substitution is explicit in the highly significant differences observed in Ru - Ru distances (2.8301(6), 2.8653(7) and 2.8873(7) A?) in the present compound compared to Ru3(CO)10(μ-Ph2AsCH2AsPh 2). The observed Ru - As distances are 2.4508(7) and 2.4331(7) A? respectively and the Ru - P distance is 2.362(1) A?. In the case of Ru3(CO)8(μ-Ph2AsCH2AsPh 2)(μ-Ph2PCH2PPh2), the chelating ligands occupy four equatorial positions. Two of the Ru - Ru distances are similar in length (2.848(2), 2.850(2) and 2.828(2) A?). However, positional disorder is associated with As and P atoms. Other bond parameters are normal.
