Carbon–beryllium Bond
Organoberyllium chemistry involves the synthesis and properties of organometallic compounds featuring the group 2 alkaline earth metal beryllium (Be). Beryllium is best known to have a +2 oxidation state and one of the smallest atoms and it is understudied in the periodic table. While metallic beryllium is relatively unreactive, its dust causes berylliosis and compounds are toxic. The Be2+ cation is characterized by the highest known charge density (Z/r = 6.45), making it one of the hardest cations and a very strong Lewis acid. It is most commonly used to coordinate other elements and can portray many types of compound through different ligands attachment. Coordination in beryllium can range from a coordination number of two to four. Most common ligands attached to beryllium are halides, hydride (like beryllium borohydride in a three-center two-electron bond), methyl, aryl, and alkyl. Beryllium can form complexes with known organic compounds such as phosphines, N-hetereocyclic c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal Structure Of A BePh2 Complex That Produce Dimers
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and " rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third categor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
