In a one-boson-exchange model, we study molecular states of double-charm baryon [\mathrm\ensuremathΞcc(3621)] and a charmed meson (D and D*). Our model indicates that there exist two possible triple-charm molecular pentaquarks, a \mathrm\ensuremathΞccD state with I(JP)=0(1/2^\ensuremath-), and a \mathrm\ensuremathΞccD* state with I(JP)=0(3/2^\ensuremath-), and we do not find bound solutions for isotriplet states. In addition, we also extend our formula to explore \mathrm\ensuremathΞccB(*), \mathrm\ensuremathΞccD(*), and \mathrm\ensuremathΞccB(*) systems and find more possible heavy flavor molecular pentaquarks, a \mathrm\ensuremathΞccB state with I(JP)=0(1/2^\ensuremath-), a \mathrm\ensuremathΞccB* state with I(JP)=0(3/2^\ensuremath-), and \mathrm\ensuremathΞccD*/\mathrm\ensuremathΞccB* states with I(JP)=0(1/2^\ensuremath-). Experimental research for these predicted triple-charm molecular pentaquarks is encouraged.
