Abstract: We consider a one-dimensional model of a two-component Bose-Einsteincondensate in the presence of periodic external potentials of opposite signs,acting on the two species. The interaction between the species is attractive,while intra-species interactions may be attractive too the system of theright-bright BB type, or of opposite signs in the two components thegap-bright GB model. We identify the existence and stability domains forsoliton complexes of the BB and GB types. The evolution of unstable solitonsleads to the establishment of oscillatory states. The increase of the strengthof the nonlinear attraction between the species results in symbioticstabilization of the complexes, despite the fact that one component is centeredaround a local maximum of the respective periodic potential.
