Multifaceted Sn–Sn bonding in the solid state. Synthesis and structural characterization of four new Ca–Li–Sn compounds

Abstract

Four new ternary Ca–Li–Sn phases have been characterized using single-crystal X-ray diffraction and ab initio calculations. The new compounds demonstrate rich diversity of Sn-based polyanionic structures with various chemical bonding patterns.

Bismuth as a Reactive Solvent in the Synthesis of Multicomponent Transition-Metal-Bearing Bismuthides

“…When possible, the application of fluxes containing exclusively those elements that constitute the targeted crystals is beneficial because it allows one to avoid the presence of foreign elements in the product. In this way, many compounds of low-melting metals, e.g., gallium, indium, and tin, can be produced using the respective metal as a reactive flux. ,− …”

Synthesis, Structural Characterization and Chemical Bonding of Sr7Li6Sn12and its Quaternary Derivatives with Eu and Alkaline Earth Metal (Mg, Ca, Ba) Substitutions. A Tale of Seven Li‐Containing Stannides and Two Complex Crystal Structures

“…Another, is the fact that by lowering the symmetry to monoclinic, a partial Li and Sn ordering is allowed. This is important for understanding the bonding within a whole class of stannides with extensive Li–Sn disorder, specifically RE 3 Li 4– x Sn 4+ x ( RE = La–Nd, Sm; x < 0.3), CaLi 9– x Sn 6+ x , Ca 9 Li 6+ x Sn 13– x , as well as Eu 7 Li 8– x Sn 10+ x ( x ≈ 2.0). Arguably, the Li and Sn ordering is most relevant to the previously discussed Li1 site in Sr 7 Li 6 Sn 12 (Table ), where the refined model has disordering between Li and Sn atoms in an almost 1:1 statistical distribution.…”

Yet Another Case of Lithium Metal Atoms and Germanium Atoms Sharing Chemistry in the Solid State: Synthesis and Structural Characterization of Ba2LiGe3

“…Reacting, in the solid state, alkali metals and/or alkaline-earth metals with the metalloids (early p-block elements) generates a large number of compounds with unusual structures. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] In particular, one should notice that the structural diversity is greatly amplified if the realization of compounds containing more than one type of alkali metals and/or alkaline-earth metals are considered. [7][8][9][10][11][12][13][14] The different nature/ratios of elements in the chemical make-up of the compound leads to varied bonding arrangements, where the atoms of the metalloid use the electrons donated by the alkali metals or alkaline-earth metals and form 2D-or 3D-networks, chains and chain-like fragments, small clusters, dumbbells, etc.…”
