Heptacoordinate transition-metal-decorated metallo-borospherenes and multiple-helix metallo-boronanotubes

Abstract

Recent discovery of the lanthanide-metal-decorated metallo-borospherenes LM3B18‒ (LM = La, Tb) marks the onset of a new class of boron-metal binary nanomaterials. Using the experimentlaly observed or theoretically predicted borospherenes...

Perfect cubic metallo-borospherenes TM8B6 (TM = Ni, Pd, Pt) as superatoms following the 18-electron rule

“…20,21 Bottom-up approaches were recently proposed at the DFT level from medium-sized bilayer boron nanoclusters to bilayer borophene nanomaterials 22 and from heptacoordinate transition-metal-decorated metallo-borospherenes to quasimultiple-helix metallo-boronanotubes. 23 Cubic Zn I 8 -bearing compounds [Zn I 8 (HL) 4 (L) 8 ] 12− (L = tetrazole dianion) have been experimentally observed, where the aromatic cubic [Zn I 8 ] motif can be used as building blocks to form self-assembled materials. 24 Transition metal (TM) clusters based on a TM 8 cube with twelve organic ligands on twelve edges have been extensively studied.…”
