Designing ionic solids from metallic clusters

WebDec 30, 2024 · Ionic Solids. Ionic solids, such as sodium chloride and nickel oxide, are composed of positive and negative ions that are held together by electrostatic attractions, which can be quite strong (Figure \(\PageIndex{3}\)).Many ionic crystals also have high melting points. This is due to the very strong attractions between the ions—in ionic … WebAn ionic solid made out of Al13 (or BAl12) and Cs is shown to be metastable and marked by a large gap at the Fermi energy even though bulk Al and Cs are metals. Designing principles for forming stable metallic clusters whose chemistry mimics different atoms of the periodic table are discussed.
