We study the production of multicharmed hadrons by recombination in heavy ion collisions by focusing on the production of Ξcc,Ξcc∗,ωscc,ωscc∗,ωccc baryons and X(3872) mesons. Starting from the estimation of yields for those hadrons at chemical freeze-out in both the statistical and coalescence models, we evaluate their transverse momentum distributions at midrapidity in the coalescence model. Considering the experimental measurements of weakly decaying singly charmed hadrons we find that yields of multicharmed hadrons in heavy ion collisions at RHIC and LHC are large enough, and thereby not only multicharmed hadrons observed so far, e.g., the Ξcc, but also those which have not been observed yet, can be discovered in heavy ion collisions. We also find that the transverse momentum distribution ratio between various multicharmed hadrons sensitively reflects the interplay between quark contents of corresponding hadrons as well as the transverse momentum distribution of charm quarks at the hadronization point, and therefore we insist that studying both the transverse momentum distributions of multicharmed hadrons themselves and transverse momentum distribution ratios between various multicharmed hadrons provide us with useful information on hadron production mechanism involving charm quarks in heavy ion collisions.
