The prominent contribution to the density of states comes from Sn-s and X-p orbitals. The optical properties suggest that Cs2SnI6 and Rb2SnI6 possess maximum optical absorption. Moreover, some of the compounds with I anions have band gap in the order of 1 eV, indicating their ability for...
the invention result from the reaction of a halogenated or oxyhalogenated Lewis acid based on titanium, niobium, tantalum, tin or antimony with an organic salt of formula X + A in which A is a halide anion and X + a quaternary ammonium, quaternary phosphonium or ternary sulphonium cation....
and in the meantime store the intermittent renewable electricity1,2,3,4. The control over the selectivity of CO2RR is a major challenge given that it can produce up to 16 different gas and/or liquid products depending on diverse reaction...
The pyramidal tetrahedral [Cu(CN)4]3− anion, in II, are interconnected by two kinds of nanometer spacers; -CN→Sn(Ph3)←O(H)H…NC– and –CN→Sn(Ph3)–N(mpym)N–Sn(Ph3)←NC– creating super-Prussian blue 3D-network structure. Graphical abstract The reaction of K3[Cu(CN)4...
Disclosed is a Ziegler-Natta catalyst for olefin polymerization comprising a metal cation of Group 4 or 14 of the Periodic Table (IUPAC 1976) that is coordinated to a. a carborane dianion group; b. a heteroatom anion, said heteroatom being preferably in
Structure refinements have been reported for the tetrastannides A4Sn4 (A = Na, K, Cs) [54, 55] and for a variety of structurally complex stannides like K4Sn9 [57, 58] or Cs52Sn82 [59] which contain the Sn94− cluster anion (Fig. 4). Many of the alkali and alkaline earth ...
1: Complete the following table below by writing the correct formula for the compound formed between each combination of cation and anion. 2: Then write the correct chemical name for each. What is the correct name of the compound whose formula is N_...
The cation of FAAc can passivate the vacancy of F A+ in the crystallization process without introducing impurity cations. The coordination between the anion CH3COO− (C=O group) with under-coordinated Sn atoms led to the formation of intermediate phase, which could slower the ...

They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components ...
