Proton-neutron asymmetry can be expected to play a much larger role in the collective structure of very neutron-rich nuclei than it does for nuclei near stability. Such proton-neutron asymmetry can provide an underlying mechanism for triaxial deformation. The possibility of qualitatively new forms of ground state structure will be examined, using the proton-neutron interacting boson model (IBM-2). The rich, multidimensional phase diagram of this model will be discussed.
