Abstract：

We study charmonium (ccnn), bottomonium (bbnn) and exotic (ccnn and bbnn) four-quark states by means of a standard non-relativistic quark potential model. We look for possible bound states. Among them we are able to distinguish between meson-meson molecules and compact four-quark states.
