摘要: Geometries and electronic structures of the B12 cluster have been investigated using a Car–Parrinello ab initio molecular dynamics simulation. The icosahedral structure, which is commonly found in bulk boron compounds, locally stable, but has few dangling bonds. On melting annealing, this structure rearranges to more open geometry. new significantly lower energy despite coordination. bonds are stronger there no
