In a multi layered close-packed structure

WebClose packed structures consist of close packed layers which fit together so that each sphere of one layer rests in a hollow between three spheres on the layers above and below. In the hexagonal close packed arrangement, the first two layers are staggered relative to one another and the third layer is on top of the first. WebThe Sm-type crystal structure is close-packed with rhombohedral symmetry, with 9-layer stacking order ABCBCACAB-ABCBCACAB, in contrast with FCC (ABC-ABC), HCP (AB-AB) and DHCP (ABAC-ABAC). The close-packed rhombohedral structure belongs to space group #166 or R-3m, Strukturbericht C19, and Pearson symbol hR3. α-Sm is the prototype.
