Professor Chen’s recent JACS paper predicted a graphene-like material with hypercoordinate transition metal

Dr. Chen recently extended the concept of planar hypercoordinate transition metal to two-dimensional (2D) nanomaterials, and predicted three FeB6 monolayers, namely α-FeB6, β-FeB6 and γ-FeB6, which consist of the Fe©Bx (x = 6, 8) wheels with planar hypercoordinate Fe atoms locating at the center of six- or eight-membered boron rings. The 2D boron networks are dramatically stabilized by the electron transfer from Fe atoms, and the FeB6 monolayers have pronounced stabilities. The α-FeB6 monolayer is metallic, while the β-FeB6 and γ-FeB6 sheets are semiconductors with indirect band gaps and significant visible-light absorptions. Besides the novel chemical bonding, the high feasibility for experimental realization, and unique electronic and optical properties, render them very welcome new members to the graphene-like materials family.
