A diquark model is used to investigate single charmed baryons. In this model, baryon is composed of two diquarks and an antiquark. Masses of lowest lying states with JP= 1/2 ^ ± are obtained. Some masses are smaller than other theoretic predictions which indicates that these baryons of pentaquark structure could be relatively stable. The results also show that Λ(2882) may be a pentaquark with JP=1/2- and Ξ(3125) may be a pentaquark with JP=1/2+.
