Borane - Generic Formula of Boranes

Generic Formula of Boranes

The four series of single-cluster boranes have the following general formulae, where "n" is the number of boron atoms:

Type formula notes
closo− BnHn2− No neutral BnHn+2 boranes are known
nido− BnHn+4
arachno− BnHn+6
hypho− BnHn+8 only adducts established

There also exists a series of substituted neutral hypercloso-boranes that have the theoretical formulae BnHn. Examples include B12(OCH2Ph)12, which is a stable derivative of hypercloso-B12H12.

Famous quotes containing the words generic and/or formula:

    “Mother” has always been a generic term synonymous with love, devotion, and sacrifice. There’s always been something mystical and reverent about them. They’re the Walter Cronkites of the human race . . . infallible, virtuous, without flaws and conceived without original sin, with no room for ambivalence.
    Erma Bombeck (20th century)

    In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.
    Alicia F. Lieberman (20th century)
