Visualizing lone pairs in compounds containing heavier congeners of the carbon and nitrogen group elements
In this mini-review, I discuss some recent work on the stereochemistry and bonding of lone pairs of electrons in divalent compounds of the heavier carbon group elements (Sn, Pb) and in trivalent compounds of the heavier nitrogen group elements (Bi). Recently developed methods that permit the real-space visualization of bonding patterns on the basis of density functional calculations of electron...

ductance of layer. These dependencies showed that hybridization appears when sheet conductance of layer (σ) exceeds some critical value σcr), the magnitude of which changes in wide range and depends on material and plate orientation. For example, for aforementioned hybrid pair A0 SH0 in potassium niobate σcr = 10−3S. If σ < σcr modes are not coupled, i.e. their dispersion curves do not repulse....
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 کاملA comparative study of the interaction of platinum with group 4A (germanium, tin and lead) porphyrins.
Because of its vast number of applications and high price many studies have been made on how to reduce the amount of platinum in catalysts. One method includes dispersing platinum nanoparticles in porous support materials. But electrically conductive carbon-based support materials-needed for fuel cell electrodes-permit nanoparticles to migrate and form larger clusters, leading to reduced cataly...
متن کاملMass Spectra of the Tetramethyl Compounds of Carbon Silicon , Germanium , Tin , and Lead 1 Vernon
Mass spectra of C(CI-I3)" Si(CI-I3)" Ge(CI-I3)" Sn(CI-I3)" and Pb (CI-Ia), were obtained with a Consolidated 21103 mass spectrometer. I sotopic abundan ces of carbon , si licon , germanium, tin, and lead were obtained from t he observed spectra and used to calculate the monoisotopic spectra. The mass spectra of t he Group IV tetramethyls a re qualitatively similar. The principal ion in each cas...
