WebOct 10, 2011 · CsCl structure is not BCC (Body Centered Cubic). It is SC (Simple Cubic) with two basis. That what says in the book. My question is, if i consider CsCl is not BCC and it can be represented by SC with two basis (CS+ and Cl-) then why can't we imagine or consider original BCC structure as a combination of SC with two basis (two Fe atoms). WebNov 9, 2024 · Is Caesium chloride FCC or BCC? Figure 3A shows the cesium chloride (CsCl) structure, which is a cubic arrangement.

Web$\begingroup$ I think that your description of the B1 and B2 structures is not the best way of describing them. You're calling B1 an fcc structure, but in truth it's something called an NaCl-structure. It can be visualized as two interpenetrating fcc sub-lattices, one made of Na atoms and the other made of Cl atoms.

In a unit cell, an atom's coordination number is the number of atoms it is touching. The simple cubic has a sphere at each corner of a cube. Each sphere has a coordination number of 6 and there is 1 atom per unit cell.
