The new trisubstituted triruthenium carbonyl cluster containing mixed P/As ligands namely Ru3(CO)9(µ-Ph2P(CH2)4PPh2)(AsPh3) was prepared by a simple ligand substitution reaction between Ru3(CO)10(µ-Ph2P(CH2)4PPh2) and AsPh3. The molecular structure and spectroscopic analysis were performed using a single-crystal X-ray diffraction, infrared spectroscopy, and nuclear magnetic resonance spectroscopy. The crystal structure of Ru3(CO)9(µ-Ph2P(CH2)4PPh2)(AsPh3) revealed a new example of trisubstituted complex with the general structure Ru3(CO)9(L-L)(ER3) (where L-L = bidentate phosphine; ER3 = Group 15 monodentate ligand) containing a long chain of bidentate phosphine ligand. The two phosphorus of Ph2P(CH2)4PPh2 and AsPh3 occupy equatorial positions on adjacent metal atoms. The longest Ru–Ru bond length is strongly influenced by the bite angle of Ph2P(CH2)4PPh2 ligand as compared to the cone angle of AsPh3. The Hirshfeld surfaces analysis has revealed that the H⋯H contacts contribute to the largest contribution of the total Hirshfeld surface. © 2024 Taylor & Francis Group, LLC.
