About:Metallocarbohedryne

An Entity of Type:Band,from Named Graph:http://dbpedia.org,within Data Space:dbpedia.org

A metallocarbohedryne (or met-car for short) is any one of a family of chemical compounds with the generic molecular formula M8C12, where M is a transition metal such as titanium, vanadium, zirconium, niobium, hafnium, molybdenum, chromium, or iron. The name is also used for the corresponding cations M8Cn+12 and anions M8Cn-12. The first papers used the name metallo-carbohedrene (with or without the hyphen) for this type of compound.

dbo:abstract
  • A metallocarbohedryne (or met-car for short) is any one of a family of chemical compounds with the generic molecular formula M8C12, where M is a transition metal such as titanium, vanadium, zirconium, niobium, hafnium, molybdenum, chromium, or iron. These compounds have similar properties and a similar molecular structure, with the eight metal atoms at the corners of a somewhat distorted cube, and the twelve carbon atoms, in pairs, placed diagonally across the faces of the cube. The structure can also be described as two intersecting tetrahedra of metal atoms, with the carbon atoms placed in pairs along the edges of one tetrahedron. They have been extensively studied in the gas phase, and sometimes dispersed in solid materials, but so far have not been produced in bulk or in solution. Nevertheless, they have attracted interest because of their stability and symmetry, a relatively low ionization potential, delayed extraction, and possibly interesting magnetic properties. Some authors suggest that they may eventually find applications in electronics and catalysis. The name is also used for the corresponding cations M8Cn+12 and anions M8Cn-12. The first papers used the name metallo-carbohedrene (with or without the hyphen) for this type of compound. (en)
