Naming Conventions
The naming of neutral boranes is illustrated by the following examples, where the Greek prefix shows the number of boron atoms and the number of hydrogen atoms is in brackets:
- B5H9 pentaborane(9)
- B6H12 hexaborane(12)
The naming of anions is illustrated by the following, where the hydrogen count is specified first followed by the boron count, and finally the overall charge in brackets:
- B5H8− octahydropentaborate(1−)
Optionally closo− nido− etc. (see above) can be added:-
- B5H9, nido−pentaborane(9)
- B4H10, arachno−tetraborane(10)
- B6H62−, hexahydro−closo−hexaborate(2−)
Understandably many of the compounds have abbreviated common names.

Famous quotes containing the words naming and/or conventions:
“Husband,
who am I to reject the naming of foods
in a time of famine?”
—Anne Sexton (1928–1974)
“I find nothing healthful or exalting in the smooth conventions of society. I do not like the close air of saloons. I begin to suspect myself to be a prisoner, though treated with all this courtesy and luxury. I pay a destructive tax in my conformity.”
—Ralph Waldo Emerson (1803–1882)
