Octahedral, trigonal prismatic, and capped square pyramidal structures have been optimized for the Ru6C(CO)n clusters (15 ≤ n ≤ 20) using density functional theory, by a team from Dalian, China and Georgia, USA. They have shown that the very stable Ru6C(CO)17 is predicted to have an octahedral structure in accord with experiment as well as the Wade–Mingos rules. In addition, the maximum number of external CO groups around an Ru6 octahedron in a stable compound appears to be 17. To find out more read the full text of this ‘Hot Article’ here.
