It can be seen in the diagram that each chloride anion has six sodium cations surrounding it and vice versa making what looks like a regular octahedron. This also means that the cations and the anions are present in the structure having a coordination ratio of 6:6 and each unit cell contai...
Owing to the tetrahedral-coordination structure of the water molecule, both of the two OH bonds of the bridging water molecule point outward along the short axis of the type-II cluster. One of the OH bonds points obliquely upward and the other forms H bond with the Cl À anion in the ...
62 Because Co3O4 has a spinel structure, valence states of transition-metal cations in either tetrahedral or octahedral interstices are variable, and the surface lattice oxygen anions have different coordination numbers, which results in different Lewis basic sites on the surface.63 These unique ...
They can form coordination bonds with empty orbits of metal elements, and adsorb on the metal surface to protect metal material [7,8,9]. Thereinto, imidazole, quinoline, pyridine, and their derivatives are most commonly used to control corrosion owing to the structure of the nitrogen-containing...
This mechanism comes from the structure of the complex molecules which contain a large number of N atoms. The lone-pair electrons on these N atoms interact chemically with the free d-orbitals of the Al metal, which favours the adsorption process of the complex on the AA2024-T3 alloy surface...
