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.
