Description: Crystal structure of left-handed and right-handed MeSi crystals (Me=Fe, Co, Mn). The top pair shows the eight atoms in the unit cell, with red, yellow, and green bars representing the three shortest interatomic distances. The middle pair includes three silicon atoms from outside the cell in order to show the polyhedron surrounding a metal atom. The polyhedron is chiral, and enantiomorphic polyhedra surround the silicon atoms. The bottom pair shows the view along the three-fold axis, and shows the locations of two enantiomorphic three-fold screw axes in each. (The unit cell on the right is rotated by 60° compared to the one on the left.) The metal atoms may appear to be at the corners of the cells in this projection, but in fact they are closer or further away from the viewer.
