$\ce{SbH3}$ and compounds derived from it by substituting one, two or three hydrogen atoms by hydrocarbyl groups $\ce{R3Sb}$. $\ce{RSbH2}$, $\ce{R2SbH}$ and $\ce{R3Sb}$ ($\ce{R} \neq \ce{H}$) are called primary, secondary and tertiary stibines, respectively. A specific stibine is preferably named as a substituted stibane. E.g. $\ce{(CH2=CH)3Sb}$ trivinylstibane.
