Chalcogen bonds, a relatively recent 'discovery', also share the same aspects of the halogen bond, including the high directionality. However, chalcogen atoms can form two highly directional chalcogen bonding interactions as a result of the presence of two σ-holes directly opposed to R-Ch bonds [23,24,25,26].

Sulfur is the second chalcogen after oxygen in the periodic table. It has 16 protons and an electron configuration of 1s2 2s 2 2p 6 3s 2 3p 4. Sulfur has six valence electrons and a vacant 3d orbital, which allows it to exist in a wide range of oxidation states (from -2 to +6). Thus it has strong electron-donating and electron-accepting ...The meaning of CHALCOGEN is any of the elements oxygen, sulfur, selenium, and tellurium.What are Chalcogens and pnictogens? Chalcogens also bond with other pnictogens, such as arsenic, antimony, and bismuth. Heavier chalcogen pnictides tend to form ribbon-like polymers instead of individual molecules. Chemical formulas of these compounds include Bi2S3 and Sb2Se3. Ternary chalcogen pnictides are also known.Such chemical property is beneficial to forming materials with high flexibility because the two-fold coordination of chalcogen atoms leads to the formation of a floppy structure 16,17, providing ...It has, however, also been reported that the reaction of aryl ditellurides with Ni 0, Pd 0, and Pt 0 may result in the cleavage of the carbon-chalcogen bond. 332-335 The oxidative addition of organochalcogen compounds to low-valent transition metal centers is considered a key step in homogeneous catalysis. 336 Complex [Pd 2 (SePh) 4 (PPh 3) 2] forms from Ph 2 Se 2 and [Pd(PPh 3) 4] in ...In the development of such applications, the identification and understanding of defects is an important issue 1.
