Clusters Ru 3 (CO) 10 (dppm) and Ru 3 (CO) 10 (dpam) on reaction with AsPh 3 and PPh 3 in refluxing n ‐hexane afford trisubstituted clusters Ru 3 (CO) 9 (dppm)AsPh 3 and Ru 3 (CO) 9 (dpam)PPh 3 , respectively. These two trisubstituted clusters are characterized by spectroscopic and single‐crystal X‐ray diffraction. Ru 3 (CO) 9 (dppm)AsPh 3 and Ru 3 (CO) 9 (dpam)PPh 3 show a triangle of ruthenium atoms, in which the bidentate and monodentate group 15 ligands occupy equatorial position and all the carbonyl units are terminally bonded. The Ru–Ru distances in Ru 3 (CO) 9 (dppm)AsPh 3 are 2.8461(7) Å, 2.8495(7) Å, and 2.8930(6) Å, with the longest distance cis to the monodentate AsPh 3 ligand. For Ru 3 (CO) 9 (dpam)PPh 3 , the Ru–Ru distances are 2.8652(2) Å, 2.8809(2) Å, and 2.8560(2) Å with the longest distance also cis to the monodenatate PPh 3 ligand.
