A model is presented that simultaneously describes shape coexistence andquadrupole and octupole collective excitations within a theoretical frameworkbased on the nuclear density functional theory and the interacting boson model.An optimal interacting-boson Hamiltonian that incorporates the configurationmixing between normal and intruder states, as well as the octupole degrees offreedom, is identified by means of self-consistent mean-field calculationsusing a universal energy density functional and a pairing interaction, withconstraints on the triaxial quadrupole and the axially-symmetric quadrupole andoctupole shape degrees of freedom. An illustrative application to thetransitional nuclei $^{72}$Ge, $^{74}$Se, $^{74}$Kr, and $^{76}$Kr shows thatthe inclusion of the intruder states and the configuration mixing significantlylower the energy levels of the excited $0^+$ states, and that the predictedlow-lying positive-parity states are characterized by the strong admixture ofnearly spherical, weakly deformed oblate, and strongly deformed prolate shapes.The low-lying negative-parity states are shown to be dominated by the deformedintruder configurations.
