Abstract
Transition-metal-doped clusters have long been attracting great attention due to their unique geometries and interesting physical and/or chemical properties. In this paper, the geometries of the lowest- and lower-energy CoKn (n = 2-12) clusters have been screened out using particle swarm optimization and first principles relaxation. The results show that except for CoK2 the other CoKn (n = 3-12) clusters are all three-dimensional structures, and CoK7 is the transition structure from which the lowest energy structures are cobalt atom-centered cage-like structures. The stability, the electronic structures, and the magnetic properties of CoKn clusters (n = 2-12) clusters are further investigated using the first principles method. The results show that the medium-sized clusters whose geometries are cage-like structures are more stable than smaller-sized clusters. The electronic configuration of CoKn clusters could be described as 1S1P1D according to the spherical jellium model. The main components of petal-shaped D molecular orbitals are Co-d and K-s states or Co-d and Co-s states, and the main components of sphere-like S molecular orbitals or spindle-like P molecular orbitals are K-s states or Co-s states. Co atoms give the main contribution to the total magnetic moments, and K atoms can either enhance or attenuate the total magnetic moments. CoKn (n = 5-8) clusters have relatively large magnetic moments, which has a relation to the strong Co-K bond and the large amount of charge transfer. CoK4 could be a magnetic superatom with a large magnetic moment of 5 μB.

Cu 12@Au 30Ag 12: a magnetic pentakis icosidodecahedron molecule with core-shell configuration. J Mol Model 2022; 28:323.

Abstract
A 54-atom trimetallic core-shell Cu12@Au30Ag12 molecule has been identified by using first-principles calculations. This molecule with Ih symmetry consists of an icosahedral 12-atom Cu core (Cu12) coated by a pentakis icosidodecahedral 42-atom Au-Ag shell (Au30Ag12) composed of an icosidodecahedral Au30 and an icosahedral Ag12. Both the molecular dynamics simulations and vibrational frequency analysis demonstrate the high stability of Cu12@Au30Ag12. The analyses for electronic properties indicate that there exists spd hybridization which is crucial to maintain the geometrical configuration of Cu12@Au30Ag12. Moreover, a total spin magnetic moment of Cu12@Au30Ag12 is found to be 4 µB, which chiefly arises from the 6 s states of Au atoms. A new type of sugar gourd-like [Cu12@Au30Ag11]n nanowire is also proposed; the results demonstrate that the nanowire exhibits metallic and magnetic behaviors. The magnetic Cu12@Au30Ag12 molecule and [Cu12@Au30Ag11]n nanowire can be promising candidates of novel magnetic nanomaterials and nanodevices.
