2022年4月25日 · Chemical bonding analyses reveal three-fold π/σ aromaticity in circular B 12 O cluster, including global 6π aromaticity, as well as spatially isolated inner 2σ aromaticity and outer 10σ aromaticity. The three-fold 6π/2σ/10σ aromaticity underlies the stability of B 12 O cluster.

氧化硼簇具有结构多样性和独特的化学键，最近的文献表明硼基配合物在富硼氧化物簇中占主导地位。在这项工作中提出了硼基化学的一个反例。使用全局结构搜索、电子结构计算和化学键分析，我们将报告两个基于硼的准平面或平面簇：b 12 o 和 b 11 au 的计算设计。

2021年9月30日 · Herein, a new aluminoborate, Cs 3 AlB 6 O 12, has been discovered by a high-temperature solution in a vacuum system. The highly polymerized [B 12 O 24] cluster, unlike the annular configuration in previously reported polyborates, is found in …

2022年4月25日 · Chemical bonding analyses reveal three-fold π/σ aromaticity in circular B12O cluster, including global 6π aromaticity, as well as spatially isolated inner 2σ aromaticity and outer 10σ...

A fundamental concept in the description of crystalline solids is that of a “Bravais lattice”. A Bravais lattice is an infinite arrangement of points (or atoms) in space that has the following property: Where n, m, p = 0, ±1, ±2, ±3, ....... are called the “primitive lattice vectors” and are said to span the lattice. These vectors are not parallel.

2019年5月23日 · Recent observations of highly symmetric Ta 2 B 6− and Ln 2 B n− (n = 7–9) clusters have established a family of inverse sandwich structures with monocyclic boron rings stabilized by two metal atoms. The study of size-selected boron and doped-boron clusters is a burgeoning field of research.

Chemical bonding analyses reveal three-fold π/σ aromaticity in circular B12O cluster, including global 6π aromaticity, as well as spatially isolated inner 2σ aromaticity and outer 10σ aromaticity. The three-fold 6π/2σ/10σ aromaticity underlies the stability of B12O cluster. This bonding picture is unknown for bare B12 cluster and its derivatives.

2017年9月27日 · Unlike graphene, borophenes exhibit remarkable structural diversity and flexibility with different patterns of hexagonal vacancies and densities in an otherwise planar triangular lattice .

2022年4月25日 · The B12O cluster is actually isoelectronic with bare B12 cluster in terms of delocalized π/σ bonding, which inherits the structural and electronic robustness of the latter. Boron oxide clusters have structural diversity and unique chemical bonding, and recent literature has shown that boronyl complexes dominate boron-rich oxide clusters.

2002年4月21日 · download the coordinates of the atoms in these pictures in XYZ format. This is the structure of BN found in Volume 18 of the Structure Reports. Wyckoff gives what he calls a ``revised'' structure, which Pearson's Handbook and other sources reference as the B k structure.
