Oxygen-molybdenum bond distances

The collision diameters of the oxide vapor molecules must be estimated. For many common vapor molecules, the collision diameters are roughly twice the average geometrical diameters as determined by molecular or atomic radii. By use of estimated molybdenum-oxygen bond distances and a proposed configuration of the Mo309 vapor molecule (5),... 

For the molybdenum and cobalt-containing cluster, the metal core is found in a butterfly arrangement, with the two molybdenum atoms as the wing tips and the N-Co-Co array as the central core. The bond distance between the oxygen of the bound NO and the molybdenum is 2.158 A. The O-Mo interaction would seem attributable to the oxophilicity of molybdenum [74].
