Antimonide Bromide
Antimonide bromides or bromide antimonides are compounds containing anions composed of bromide (Br−) and antimonide (Sb3−). They can be considered as mixed anion compounds. They are in the category of pnictidehalides. Related compounds include the antimonide chlorides, antimonide iodides, arsenide chlorides, arsenide bromides, arsenide iodides, phosphide chlorides, phosphide bromides, and phosphide iodides. The bromoantimonates have antimony in positive oxidation states. The antimony can be linked into chains, in which case it has a formal oxidation state of −1. Alternately it can be in pairs as Sb2, with an oxidation state of −2 for each atom. Many of these compounds are clathrates A clathrate is a chemical substance consisting of a lattice that traps or contains molecules.

Mixed Anion Compound
Mixed anion compounds, heteroanionic materials or mixed anion materials are chemical compounds containing cations and more than one kind of anion. The compounds contain a single phase, rather than just a mixture. Use in materials science By having more than one anion, many more compounds can be made, and properties tuned to desirable values. In terms of optics, properties include laser damage threshold, refractive index, birefringence, absorption particularly in the ultraviolet or near infrared, non-linearity. Mechanical properties can include ability to grow a large crystal, ability to form a thin layer, strength, or brittleness. Thermal properties can include melting point, thermal stability, phase transition temperatures, Thermal expansion coefficient. For electrical properties, electric conductivity, band gap, superconducting transition temperature piezoelectricity, pyroelectricity, ferromagnetism, dielectric constant, charge-density wave transition can be adjus ...

Antimonide Chloride
Antimonides (sometimes called stibnides) are compounds of antimony with more electropositive elements. The antimonide ion is Sb3−. Reduction of antimony by alkali metals or by other methods leads to alkali metal antimonides of various types. Known antimonides include isolated Sb3− ions (in Li3Sb, Na3Sb), dumbbells Sb24− in Cs4Sb2, discrete antimony chains, for example, Sb68− in SrSb3, infinite spirals (Sb−)n (in NaSb, RbSb), planar four-membered rings Sb42−, Sb73− cages in Cs3Sb, and net shaped anions Sb32− in BaSb3. Some antimonides are semiconductors, e.g. those of the boron group such as indium antimonide. Many antimonides are flammable or decomposed by oxygen when heated since the antimonide ion is a reducing agent.

Although antimony tribromide is known, SbBr5 on its own does not exist, despite the existence of . Compounds containing both Sb(III) and Sb(V) are mixed valence compounds. The antimony can be linked into chains, (which are called one-dimensional as it is like a line), or in pairs as Sb2 or singly as Sb (which are called zero-dimensional, as the anions are just point-like). Tetrabromoantimonate(III) (SbBr4−) has single antimony atoms in each anion. SbBr52− contains infinite chains o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clathrate Compound
A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word ''clathrate'' is derived from the Latin (), meaning ‘with bars, latticed’. Most clathrate compounds are polymeric and completely envelop the guest molecule, but in modern usage clathrates also include host–guest complexes and inclusion compounds.Atwood, J. L. (2012) "Inclusion Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry''. Wiley-VCH, Weinheim. According to IUPAC, clathrates are inclusion compounds "in which the guest molecule is in a cage formed by the host molecule or by a lattice of host molecules." The term refers to many molecular hosts, including calixarenes and cyclodextrins and even some inorganic polymers such as zeolites. Clathrates can be divided into two categories: clathrate hydrates and inorganic clathrates. Each clathrate is made up of a framework and guests that reside the framework. Most common clathrate crystal structures can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
