Chemical Bonding of Main-Group Elements
Prior to any meaningful discussion of bonding in main-group chemistry, we have to provide a reasonably accurate definition of what a main-group element is. In general, we assume that main-group elements are those that essentially use only their valence sand p-orbitals for chemical bonding. This leads to a number of borderline cases that require closer inspection. Assuming that the outer d-orbit...
متن کاملIminophosphanes: Unconventional Compounds of Main Group Elements
The large number of known stable compounds in which phosphorus has a low coordination number makes it clear that such compounds can no longer be regarded as “exotic” in main group chemistry. While the rich chemistry of P-C multiply bonded systems makes clear their affinity to their organic congeners, iminophosphanes in particular are also of increasing importance. The linkage of a phosphinidine...
متن کاملSuperconductivity in Hydrides Doped with Main Group Elements Under Pressure
A priori crystal structure prediction techniques have been used to explore the phase diagrams of hydrides ofmain group elements under pressure. Anumber of novel phases with the chemical formulas MHn, n > 1 and M = Li, Na, K, Rb, Cs; MHn, n > 2 and M= Mg, Ca, Sr, Ba; HnI with n > 1 and PH, PH2, PH3 have been predicted to be stable at pressures achievable in diamond anvil cells. The hydrogenic la...
متن کاملResearch Articles Photocontrol of the Coordination Numbers of the Main Group Elements: Properties of Azobenzenes Bearing a Main-Group-Element Substituent and Their Application | TCI
Each main group element in main group compounds usually takes its own specific coordination number, oxidation number and bonding state. An unusual valence can be achieved by appropriate molecular design and synthetic methods, and such an unusual valence results in characteristic, unique structures and properties. The reactivity of the main group compounds markedly depends on the coordination nu...
متن کاملControlled Synthesis of Polyions of Heavy Main-Group Elements in Ionic Liquids
Ionic liquids (ILs) have been proven to be valuable reaction media for the synthesis of inorganic materials among an abundance of other applications in different fields of chemistry. Up to now, the syntheses have remained mostly "black boxes"; and researchers have to resort to trial-and-error in order to establish a new synthetic route to a specific compound. This review comprises decisive reac...
