We study the structure-dependent contributions to the radiative baryonic $B$ decays of $B ｴto {ｴbf B}{ｴbf ｴbar B\'}ｴgamma$ in the standard model. We show that the decay branching ratios of $Br(B ｴto {ｴbf B}{ｴbf ｴbar B\'}ｴgamma)$ are $O(10^{-7})$, which are larger than the estimated values of $O(10^{-9})$ induced from inner bremsstrahlung effects of the corresponding two-body modes. In particular, we find that $Br(B^- ｴto ｴLambda ｴbar p ｴgamma)$ is around $1 ｴtimes 10^{-6}$, which is close to the pole model estimation but smaller than the experimental measurement from BELLE.
