The nonmetallicity of molybdenum clusters

The Journal of Chemical Physics, 2004
Molybdenum clusters consisting of 2–55 atoms were investigated using density functional theory calculations with a plane-wave basis set. The results show that the linear and planar molybdenum clusters have a strong tendency to form dimers. This tendency results in the formation of alternate short and long bonds within a linear cluster, in which the ...
