Structure and properties of Ni7 cluster isomers - ScienceDirect
May 10, 1996 · We show for the first time that a global optimization of NiT using molecular dynamics as well as ab initio molecular orbital theory yields two nearly degenerate isomeric structures - a capped octahedron and a pen- tagonal bipyramid. However, the catchment area for the capped octahedron is much higher than the pentag- onal bipyramid.
