Polymorphism in NaSbO3: structure and bonding in metal oxides.
A new polymorph of NaSbO(3) has been synthesized at 10.5 GPa and 1150 degrees C in a uniaxial split sphere anvil type press (USSA-2000) and recovered back to ambient conditions. The high-pressure form of NaSbO(3) adopts an orthorhombically distorted perovskite structure, isostructural with CaTiO(3), GdFeO(3), and NaTaO(3). The space group is Pnma, and the unit cell dimensions are a = 5.43835(6)...
متن کاملEmbedding transition-metal atoms in graphene: structure, bonding, and magnetism.
We present a density-functional-theory study of transition-metal atoms (Sc-Zn, Pt, and Au) embedded in single and double vacancies (SV and DV) in a graphene sheet. We show that for most metals, the bonding is strong and the metal-vacancy complexes exhibit interesting magnetic behavior. In particular, an Fe atom on a SV is not magnetic, while the Fe@DV complex has a high magnetic moment. Surpris...
متن کاملUnderstanding Structure and Bonding of Multilayered Metal–Organic Nanostructures
For organic and hybrid electronic devices, the physicochemical properties of the contained interfaces play a dominant role. To disentangle the various interactions occurring at such heterointerfaces, we here model a complex, yet prototypical, three-component system consisting of a Cu-phthalocyanine (CuPc) film on a 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA) monolayer adsorbed on Ag(1...
متن کاملStructure and Bonding
A molecule is formed by the combination of atoms and in the process they attain the electronic configuration of an inert gas. A chemical bond is formed as a result of attraction between the combining atoms. To explain the formation of bonds in diatomic molecules, such as H2, O2, N2, Cl2 etc., it was first suggested by G.N. Lewis that atoms of such molecules attain an inert gas electronic config...
متن کاملMetal-metal bonding in sterically frustrated dipalladium species.
Stoichiometric-deficient lithiation of (2,6-diisopropylphenyl)(4-methylpyridin-2-yl)amine and reaction with [(cod)PdCl2] (cod = 1,5-cyclooctadiene) yield a dimeric Pd complex. X-ray structural analysis of this complex reveals a very short Pd-Pd distance (2.429 A). Topological analysis of the electron density and the electron localization function from scalar relativistic density functional theo...
