How are motifs and crystal systems related
WebIf we look carefully at these drawings, we will discover that there is always a fraction of them that is repeated. In crystals, the atoms, ions or molecules are packed in such a way that they give rise to "motifs" (a given set or unit) that are repeated every 5 Angstrom, up to the hundreds of Angstrom (1 Angstrom = 10-8 cm), and this repetition, in three dimensions, … WebThe table at the bottom of this page lists the 230 three-dimensional space groups used by crystallographers to describe the symmetry of their crystal structures. The space groups …
