From inverse sandwich Ta₂B₇ ⁺ and Ta₂B₈ to spherical trihedral Ta₃B₁₂ ^-: prediction of the smallest metallo-borospherene.

ABSTRACT: Transition-metal-doped boron nanoclusters exhibit interesting structures and bonding. Inspired by the experimentally discovered inverse sandwich D _6h Ta₂B₆ and spherical trihedral D _3h La₃B₁₈ ^- and based on extensive first-principles theory calculations, we predict herein the structural transition from perfect di-metal-doped inverse sandwich D _7h Ta₂B₇ ⁺ (1) and D _8h Ta₂B₈ (2) to tri-metal-doped spherical trihedral D _3h Ta₃B₁₂ ^- (3). As the smallest metallo-borospherene reported to date, Ta₃B₁₂ ^- (3) contains three octa-coordina
