We explore molecular states of two open heavy-quark mesons $(Q\overline{q})\ensuremath{-}(q\overline{Q})$ in a quark-based model in terms of a four-body nonrelativistic Hamiltonian with pairwise effective interactions. Molecular states are found in the combinations of ${D,{D}^{*},B,{B}^{*}}$ with ${\overline{D},{\overline{D}}^{*},\overline{B},{\overline{B}}^{*}}$, including a weakly bound $D{\overline{D}}^{*}$ state near the threshold which may be qualitatively identified as the 3872 state observed recently by the Belle Collaboration.
