  We explore the existence of $D \Xi$ and $D^* \Xi$ molecular states within the
one boson exchange model. We regularize the potential derived in this model
with a form factor and a cut-off of the order of $1\,{\rm GeV}$. To determine
the cut-off, we use the condition that the $X(3872)$ is reproduced as a pole in
the $J^{PC} = 1^{++}$ $D^*\bar{D}$ amplitude. From this we find that the $J^P=
{\frac{1}{2}}^{-}$ $D^*\,\Xi$ system is on the verge of binding and has an
unnaturally large scattering length. For the $J^P= {\frac{1}{2}}^{-}$ $D\,\Xi$
and the $J^P= {\frac{3}{2}}^{-}$ $D^*\,\Xi$ systems the attraction is not
enough to form a bound state. From heavy quark symmetry and the quark model we
can extend the previous model to the $P \Xi_{QQ}$ and $P^* \Xi_{QQ}$ systems,
with $P = D, \bar{B}$, $P^* = D^*, \bar{B}^*$ and $\Xi_{QQ} = \Xi_{cc},
\Xi_{bb}$. In this case we predict a series of triply heavy pentaquark-like
molecules.
