The generalized two-center cluster model (GTCM), which can handle various single particle configurations in general two center systems, is applied to the light neutron-rich system, {sup 12}Be = {alpha}+{alpha}+4N. We discuss the change of the neutrons' configuration around two {alpha}-cores as a variation of an excitation energy. We show that the excess neutrons form various chemical-bondinglike configurations around two {alpha} cores in the unbound region above the {alpha} decay threshold. The possibility of the {alpha} cluster formation in the heavier neutron-excess system, {sup 28}Ne, is also discussed.
