Le groupe despace dun cristal est constitue par lensemble des symetries dune structure. Dans les cristaux, il n est pas possible d avoir des rotationsrotore exions d ordre n quelconques. Equivalently, a space group is symmorphic if it is a semidirect product of its point group with its translation subgroup. Les structures cristallines peuvent donc etre classees, selon leur symetrie, en 230 groupes spatiaux ou groupes despace. Cristallographie geometrique et radiocristallographie.
