Inorganica Chimica Acta, 1976
Abstract Studies of the rates of reaction of the Group VI-B metal hexacarbonyls (M = Cr, Mo, W) with benzylamine, cyclohexylamine and aniline (amine) support a rate law, −d[M(CO) 6 ] /dt = k 1 [M(CO) 6] + k 2 [M9CO)6] [amine]. The rate law is suggestive of two competing mechanisms, with the amine-independent path involving rate-determining ...

Porous Manganese Oxide Octahedral Molecular Sieves and Octahedral Layered Materials
Accounts of Chemical Research, 2008This Account first gives a historical overview of the development of octahedral molecular sieve (OMS) and octahedral layer (OL) materials based on porous mixed-valent manganese oxides. Unique properties of such systems include excellent semiconductivity and porosity.

Some Interesting Octahedral Compounds
The Mathematical Gazette, 1968In the last paragraph of an article entitled “Octahedra Inscribed in a Cube” by T. Bakos, Math. Gazette , Vol. XLIII pp. 17-20, (1959), the following statement is made: “About a cube ( ±b, ±b, ±b ) one can circumscribe 3 regular octahedra (the edges of ...

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1963
AbstractIn the first part of this paper the formation processes of pure octahedral hydroxides are investigated. Conditions of synthesis of aluminum, magnesium, iron and mixed Al-Mg, Al-Ca, Al-Fe systems are successively reviewed. In every case crystal growth in deionized medium allows one to figure out genetic conditions.The second part deals with the ...

Nature, 1965
THE bonding in the Mo6Cl84+ and Ta6Cl122+ cations, both of which contain an octahedron of metal atoms, has recently been rationalized in terms of a 40-electron model1. The edges of the metal octahedron define the orientation of twelve bonds (type A) while the faces of the octahedron define the position of another eight (type B). In Mo6Cl84+ twenty-four
