BiH3 and compounds derived from it by substituting one, two or three hydrogen atoms by hydrocarbyl groups:
R3Bi,
RBiH2,
R2BiH (
R ≠
H) are called primary, secondary and tertiary bismuthines, respectively. A specific bismuthine is preferably named as a substituted bismuthane, e.g.
(CH3)3Bi trimethylbismuthane.
