Single-Atom-Kernelled Nanocluster Catalyst

Nano Letters, 2022
To propose the concept of single-atom-kernelled nanocluster, we synthesized a Pd-based trimetal nanocluster with a single-Ag atom-kernel for the first time by introducing some steric hindrance factors and employing a joint alloying strategy that combines

Engineering molecular rotor-stator ligand architectures on copper nanoclusters for efficient photothermal conversion [PDF]

Nature Communications
Copper nanoclusters represent a promising yet underdeveloped frontier in materials science. Here, we propose a general and efficient strategy for enhancing photothermal conversion efficiency through the incorporation of rotor-stator ligand architectures ...

Chemical Bonding and Dynamic Structural Fluxionality of a Boron-Based Na₅B₇ Sandwich Cluster

Molecules, 2023
Doping alkali metals into boron clusters can effectively compensate for the intrinsic electron deficiency of boron and lead to interesting boron-based binary clusters, owing to the small electronegativity of the former elements.

σ-Aromatic MAl₆S₆ (M = Ni, Pd, Pt) Stars Containing Planar Hexacoordinate Transition Metals

Molecules, 2023
Hypercoordinate transition-metal species are mainly dominated by the 18-valence-electron (18ve) counting. Herein, we report ternary MAl6S6 (M = Ni, Pd, Pt) clusters with the planar hexacoordinate metal (phM) centers, which feature 16ve counting instead ...

Boron Oxide B5O6− Cluster as a Boronyl-Based Inorganic Analog of Phenolate Anion

Frontiers in Chemistry, 2022
Boron oxide clusters have structural richness and exotic chemical bonding. We report a quantum chemical study on the binary B5O6− cluster, which is relatively oxygen-rich. A global structural search reveals planar C2v (1A1) geometry as the global minimum

CAl₄X₄ (X = Te, Po): Double Aromatic Molecular Stars Containing Planar Tetracoordinate Carbon Atoms

Molecules, 2023
Planar tetracoordinate carbon (ptC) species are scarce and exotic. Introducing four peripheral Te/Po auxiliary atoms is an effective strategy to flatten the tetrahedral structure of CAl4 (Td, 1A1).

Boron-lead multiple bonds in the PbB2O– and PbB3O2 – clusters

Communications Chemistry, 2022
Despite its electron deficiency, boron can form multiple bonds with a variety of elements, but such bonds between boron and main-group metal elements are relatively rare.

Ternary XBe₄H₅⁻ (X = Si, Ge, Sn, Pb) Clusters: Planar Tetracoordinate Si/Ge/Sn/Pb Species with 18 Valence Electrons

Molecules, 2023
As one of the important probes of chemical bonding, planar tetracoordinate carbon (ptC) compounds have been receiving much attention. Compared with ptC clusters, the heavier planar tetracoordinate silicon, germanium, tin, lead (ptSi/Ge/Sn/Pb) systems are

Boron-Based Inverse Sandwich V₂B₇⁻ Cluster: Double π/σ Aromaticity, Metal–Metal Bonding, and Chemical Analogy to Planar Hypercoordinate Molecular Wheels

Molecules, 2023
Inverse sandwich clusters composed of a monocyclic boron ring and two capping transition metal atoms are interesting alloy cluster systems, yet their chemical bonding nature has not been sufficiently elucidated to date.
