We study the two- baryon system with two units of charm looking for the possible existence of a loosely bound state resembling the H dibaryon. We make use of a chiral constituent quark model tuned in the description of the baryon and meson spectra as well as the NN interaction. The presence of the heavy quarks makes the interaction simpler than in light baryon systems. We analyze possible quark- Pauli effects that would be present in spin- isospin saturated channels. Our results point to the nonexistence of a charmed H- like dibaryon, although it may appear as a resonance above the Lambda(c)Lambda(c) threshold.
