Organoboron Compounds

Rule D-7.6 Organoboron Coordination Compounds

7.62 - Organoboron coordination compounds in which the boron atom has coordination number 4 and in which one or more boron atoms is charged are named as coordination compounds, using the name borate, if the coordination entity is negatively charged, or the name borone, if the coordination entity is positively charged. The charge is given by the appropriate Ewens-Bassett number enclosed in parentheses following the name.

Examples to Rule D-7.62


Tetramethylborate(1-)

Hexaphenyldibarate(2-)

Hydropentamethyldiborate(2-)

Tridecahydro(pyridine)decaborate(1-)

Trifluoro[(triphenylphosphonio)-methyl]borate

Dihydrobis(pyridine)boron(1+)

Bis(2,4-pentanedionato)boron(1+) chloride

Bis(pyridine)[3-(2-pyridyl)propyl]boron(2+)

[1,3,5-Cyclohexanetriolato(3-)]hydroxoborate(1-)

Methoxo[methyltris(2-oxidoethyl)ammonium-O,O,O]borate

7.63 - (Partly alternative to Rule D-7.62). Organoboron compounds in which a charged boron atom is in a ring system may also be named by means of replacement nomenclature. Anionic boron atoms are designated by replacement prefix borata and cationic boron atoms by the replacement prefix borylia.

Examples to Rule D-7.63

1,1-Dimethyl-1-boratacyclohexane

1-Methoxy-1,3-dimethyl-1-borataindene

(2,2-Bipyridine)(oxydi-o-phenylene)boron(1+) perchlorate

[2,2-[1,8-naphthylenebis(nitrilomethylidyne)]diphenolato-
O,N,N,O]boron(1+) perchlorate
