The atomic geometry of the (1 x 2) Bi reconstruction on the InAs(110) surface was fully determined by means of grazing incidence X-ray diffraction. The (1 x 2) Bi phase was characterized by couples of inequivalent Bi chains bonded alternatively to In and As atoms. The chains were strongly buckled with respect to the (110) InAs plane and they could easily accommodate if the InAs(110) substrate presents alternate missing rows in the [1¯10] direction.
