SbH3 and compounds derived from it by substituting one, two or three hydrogen atoms by @H02891@ groups R3Sb. RSbH2, R2SbH and R3Sb (RH) are called primary, secondary and tertiary stibines, respectively. A specific stibine is preferably named as a substituted stibane. E.g. (CH2=CH)3Sb trivinylstibane.
