In a multi layered close-packed structure
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. WebIn two-dimensional close packing, a row of closed packed spheres are stacked to obtain a two-dimensional pattern. This stacking is done in two ways: Square close packing: Packing in Solids: One and Two Dimensions The second row can be placed exactly below the first row in a close packing.
