Abstract: | Three new triruthenium clusters, Ru3(CO)9(μ‐arphos)AsPh3 ( 1 ), Ru3(CO)9(μ‐arphos)As(m‐C6H4Me)3 ( 2 ), and Ru3(CO)9(μ‐arphos)As(p‐C6H4Me)3 ( 3 ) were synthesized via thermal reactions of Ru3(CO)10(μ‐arphos) with different tertiary arsine ligands AsPh3, As(m‐C6H4Me)3, As(p‐C6H4Me)3]. All these complexes were fully characterized by elemental analysis, FT‐IR, NMR spectroscopy, and single‐crystal X‐ray diffraction. |
