Interestingly, the left and right halves of each cage are like two IMEFs connected in reverse series.

Theoretical Study of Alkaline-Earth Metal (Be, Mg, and Ca)-Substituted Aluminum Nitride Nanocages With High Stability and Large Nonlinear Optical Responses.

By replacing one Al or N atom of aluminum nitride nanocage AlN with an alkaline-earth metal atom, two series of compounds, namely, M@AlN and M@AlN (M = Be, Mg, and Ca), were constructed and investigated in theory. The substituted effect of alkaline-earth metal on the geometric structure and electronic properties of AlN is studied in detail by density functional theory (DFT) methods. The calculated binding energies, HOMO-LUMO gaps, and VIE values of these compounds reveal that they possess high stability, though the NBO and HOMO analyses show that they are also excess electron compounds.

Can a molecular switch exist in both superalkali electride and superalkalide forms?

To combine both electride and alkalide characteristics in one molecular switch, it is shown herein that the phenalenyl radical and the M ring (M-PHY, M = Li, Na, and K) stacked with parallel and vertical geometries are good candidates. The former geometry is the superalkali electride e⋯M-PHY while the latter geometry is the superalkalide M-M-PHY. The superalkalide M-M-PHY may isomerize to the superalkali electride e⋯M-PHY (M = Li, Na, and K) using suitable long-wavelength irradiation, while the latter may isomerize to the former with suitable short-wavelength irradiation.

The possibility of using coinage metal atoms as excess electron acceptors is examined for the first time by designing a new class of M-1-M' (M = Li, Na, and K; M' = Cu, Ag, and Au) compounds termed "coinage metalides" on the basis of an intriguing Janus-type all-cis1,2,3,4,5,6-hexafluorocyclohexane (1) molecule. Under the large facial polarization of 1, the outermost ns electrons of alkali metal atoms can be transferred to coinage metal atoms, forming diffuse excess electrons around them. Consequently, the resulting M-1-Cu and M-1-Ag compounds exhibit significantly large nonlinear optical (NLO) responses.

The potential application of the jellium model as guidance in the rational design of bimetallic superalkali cations is examined under gradient-corrected density functional theory for the first time. By using Li, Mg, and Al as atomic building blocks, a series of bimetallic cationic clusters with 2, 8, 20, and 40 valence electrons are obtained and investigated. As the corresponding neutral clusters tend to lose one valence electron to achieve closed-shell states in the jellium model, these studied cations exhibit much lower vertical electron affinities (EA , 3.

Theoretical investigation on the low-energy isomer identification, structural evolution, stability, and electronic properties of AlBe (x = 1-9) nanoalloys.

Numerous isomeric equilibrium structures have been identified for the AlBe (x = 1-9) nanoalloy clusters by using the stochastic search procedure in combination with density functional theory calculations. The relative stability and various electronic properties of the lowest-energy AlBe (x = 0-10) clusters have been systematically studied by using the B3LYP and CCSD(T) methods with the aug-cc-pVDZ basis set. The evolution of the binding energies, the second difference in energy, HOMO-LUMO gaps, vertical detachment energies, vertical ionization potentials, vertical electron affinities, and hardness with the increasing number of Be atoms in the most stable AlBe (x = 0-10) clusters demonstrates that the global minimum of AlBe cluster possesses a special stability.

Calculational results show that all the superalkali moieties preserve their geometric and electronic integrity in these proposed cations.
