Mn@B 3 N 3 Si 8 + : a stable singlet manganese-doped hetero-atom-mixed silicon fullerene

Hung Tan Pham, Minh Tho Nguyen, Huyen Thi Nguyen


A B3N3Si8 cage is formed upon substitution of Si sites of rhombus faces of the pure Si14 cluster by B and N atoms. Doping by the ion Mn+ leads to the hetero-silicon fullerene B3N3Si8Mn+ which comprises three rhombi (BNBN, Si3B and Si3N) and four pentagons (two Si2B2N and two Si2BN2). Hetero-atoms form polarized Si-N and Si-B bonds as indicated by electron localization function (ELF) maps and NBO charges. The Mn center connects the B3N3Si8 cage by ionic interactions. Valence electrons of B3N3Si8Mn+ occupy a shell configuration of [1S2 1P6 1D10 1F14 1G12 2S2 2P6 2D10] and induce a certain thermodynamic stability. The high spin of the Mn+ metal cation is completely quenched within the hetero-Si fullerene.
