Abstract
A series of anionic transition metal halides, OsCln- (n = 3-5), have been investigated using a newly developed, home-constructed, cryogenic anion cluster photoelectron spectroscopy. The target anionic species are generated through collision-induced dissociation in a two-stage ion funnel. The measured vertical detachment energies (VDEs) are 3.48, 4.54, and 4.81 eV for n = 3, 4, and 5, respectively. Density functional theory calculations at the B3LYP-D3(BJ)//aug-cc-pVTZ(-pp) level predict the lowest energy structures of the atomic form of OsCln- (n = 3-5) to be a quintet triangle, quartet square, and quintet square-based pyramid, respectively. The CCSD(T)-calculated VDEs and corresponding adiabatic detachment energies agree well with our experimental measurements. Analysis of the corresponding frontier molecular orbitals and charge density differences suggests that the d-orbitals of the transition metal Os play a primary role in the single-photon detachment processes, and the detached electrons originating from different molecular orbitals are distinguishable.

Abstract
![]()
Photoelectron spectroscopy
has been used to study the electronic
structure, photodetachment, and photodissociation of the stable diplatinum
iodide dianions [Pt2I6]2– and
[Pt2I8]2–. Photoelectron spectra
over a range of photon energies show the characteristic absence of
low kinetic energy photoelectrons expected for dianions as a result
of the repulsive Coulomb barrier (RCB). Vertical detachment energies
of ∼1.6 and ∼1.9 eV and minimum RCBs of ∼1.2
and ∼1.3 eV are reported for [Pt2I6]2– and [Pt2I8]2–, respectively. Both of the diplatinum halides exhibit three direct
detachment channels with distinct anisotropies, analogous to the previously
reported spectra for PtI2– and PtI–, suggesting a platinum-centered molecular core that
dominates the photodetachment. Additionally, evidence for two-photon
photodissociation and subsequent photodetachment channels producing
I– are observed for both dianions. Finally, an unexplained
feature is observed at photon energies around 3 eV, whose origin is
considered. Our work highlights the complex electronic structure of
the heavy platinum-halide dianions that are characterized by a dense
manifold of electronic states.

Abstract
The photoelectron imaging of PtI2 - is presented over photon energies ranging from hν = 3.2 to 4.5 eV. The electron affinity of PtI2 is found to be 3.4 ± 0.1 eV, and the photoelectron spectrum contains three distinct peaks corresponding to three low-lying neutral states. Using a simple d-block model and the measured photoelectron angular distributions, the three states are tentatively assigned. Photodissociation of PtI2 - is also observed, leading to the formation of I- and of PtI-. The latter allows us to determine the electron affinity of PtI to be 2.35 ± 0.10 eV. The spectrum of PtI- is similarly structured with three peaks which, again, can be tentatively assigned using a similar model that agrees with the photoelectron angular distributions.

Abstract
The ground states of the neutral and anionic tetrafluoride and hexafluoride series of 3d-metal atoms from Sc to Zn were assigned by using a double-check approach in which the pure and hybrid density functional methods were interchangeably used. It was confirmed that all these neutral fluorides are superhalogens except for TiF4. The electron affinities of the hexafluorides were shown to be consistently higher than those of the tetrafluorides in accordance with the superhalogen conception of the extra electron delocalization over a larger number of the electronegative ligands. In the search for mononuclear fluorides possessing higher electron affinities, we considered the M(F2)6- and M(F3)6- series where M = Sc-Zn. We found that the optimized geometrical structures in both series may be described as MF6-- k(F2), k = 3 and 6, of which the geometry of the MF6- core mimics that of the corresponding hexafluoride anion and the F2 dimers are kept in a bound state by polarizing forces. In these cases, the electron affinity is decreased by tenths of eV with respect to the electron affinity of the core hexafluorides due to a confinement of the extra electron by the F2 environment.

Abstract
Au2n Cl- (n = 1-4) clusters are investigated by both laser ablation mass spectrometry and theoretical calculations. It is interesting to find that the electron affinities of neutral Au2n Cl (n = 1-4) clusters are much larger than those of corresponding pure Au2n clusters. Among them, the electron affinity of Au2Cl is 4.02 eV, which can be defined as a very unique superhalogen that is quite different from classical ones of M n X m (M = metal, X = halogen, and n < m). Natural bond orbital and highest occupied molecular orbital analyses indicate that the extra electron is predominantly delocalized over the positively charged metal moiety in these anionic Au2n Cl- clusters, which is the main reason for the large electron affinities of the corresponding neutral species.

Abstract
Laser ablation mass spectrometry was applied to study the cluster anions of Pt2Cl n-. Among them, Pt2Cl6- and Pt2Cl9- were observed with remarkable intensities in the mass spectrum. Collision-activated dissociation experiments were also performed for the two anions. A systematic study of the structures and electron affinities (EAs) of Pt1-2Cl n (2 ≤ n ≤ 10) clusters was performed on the level of B3LYP/Lanl2dz/6-311++G(2d, p). For both systems, their EAs do not increase monotonically with the increase of Cl atoms. All the clusters of PtCl n (3 ≤ n ≤ 10) and Pt2Cl n (3 ≤ n ≤ 10) show EAs larger than that of the Cl atom. The highest EAs for the series of Pt2Cl n and PtCl n are 6.55 and 5.82 eV, corresponding to those of Pt2Cl9 and PtCl9, respectively. The results indicate that these clusters might be applied as effective units in constructing new "hypersalts".

Abstract
Inorganic boron nitride (BN) nanomaterials possess outstanding physical and chemical characteristics, and can be considered as an excellent building block to construct new composite nanomaterials. In this work, on the basis of the first-principles computations, a new type of composite nanostructure can be constructed by depositing superhalogen Al13 on the surface of low-dimensional BN monolayer or nanoribbons (BNML/BNNRs). All these Al13-modified BN nanosystems can possess large adsorption energies, indicating that superhalogen Al13 can be stably adsorbed on the surface of these BN materials. In particular, it is revealed that independent of the chirality, ribbon width and adsorption site, introducing superhalogen Al13 can endow the BN-based composite systems with a magnetic ground state with a magnetic moment of about 1.00 μB, and effectively narrow their robust wide band gaps. These new superhalogen-Al13@BN composite nanostructures, with magnetism and an appropriate band gap, can be very promising to be applied in multifunctional nanodevices in the near future.
