The InSb(111)A surface is prepared by molecular beam epitaxy and investigated by reflection high-energy electron diffraction (RHEED). The complete two dimensional diffraction pattern is mapped out by azimuthal RHEED (ARHEED). Two reconstructions are identified and additionally a set of new symmetries is observed. At low temperature a $$(2sqrt{3}times 2sqrt{3})$$ pattern is observed which changes to the $$(2times 2)$$ pattern at high temperature. In contrast to the GaSb(111)A surface the observed $$(2sqrt{3}times 2sqrt{3})$$ structure is not stabilized by configurational entropy.
