IR-10.3.3 Organometallic compounds of groups 1 3–16

Organometallic compounds of the elements of groups 13–16 a re named according to the
substitutive system of nomenclature, dealt with in Chapter I R-6. Thus, the name of the
parent hydride (formed in accordance with the rules of Section IR-6.2) i s m odified by a
prefix for each substituent r eplacing a h ydrogen atom of the parent hydride. The prefix
should be in appropriate substituent f orm (chloro, m ethyl, sulfanylidene, etc.) a nd not in
ligand form (chlorido, m ethanido, sulfido, etc.).
Where there is more than one kind of substituent, the prefixes a re cited in alphabetical
order before the name o f t he parent hydride, parentheses being used to avoid a mbiguity, and
multiplicative prefixes being used as necessary. Non-standard bonding numbers are
indicated using the l-convention (see Section IR-6.2.2.2). An overview of the rules for
naming substituted derivatives of parent hydrides is given i n S ection IR-6.3, w hile a d etailed
exposition may be found in Ref. 3.
