We consider planar central configurations of the Newtonian k n-body problem consisting in k groups of regular n-gons where all n bodies in each group have the same mass, called (k, n)-crown. We study the location and the number of central configurations when k=2.  For n=3 the number of central configurations varies depending on the mass ratio, whereas for n>=4 the number is at least three.  We also prove that for n>=3  there always exist three disjoint regions where the configuration can be located. Finally, we study which (k, n)-crowns are convex.
