What is difference between structure of NaCl and CsCl?

CsCl and NaCl do not adopt identical crystal packing arrangements because the Cs + ion is considerably larger than the Na + ion. In a cesium chloride crystal, the cesium ion (orange) occupies the center, while the chloride ions (green) occupy each corner of the cube. The coordination number for both ions is 8.

What is the structure of cesium chloride?

CsCl
Caesium chloride/Formula

Is CsCl FCC or BCC?

Figure 3A shows the cesium chloride (CsCl) structure, which is a cubic arrangement. If all atoms in this structure are of the same species, it is a bcc lattice. The spheres occupy 68 percent of the volume. The cesium chloride lattice (Figure 3A) is based on the bcc structure; every other atom is cesium or chlorine.

Is CsCl fcc lattice?

CsCl has a cubic structure that consists of an infinite chain of ions. The Cs (or Cl) ions sit at the eight corners of the cube and the Cl (or Cs) sit at the center of the cube (thus it is NOT a body-centered lattice since that requires the SAME ion to occupy the edges and center). The CN of both cation and anion is 8.

What is NaCl crystal structure?

NaCl has a cubic unit cell. It is best thought of as a face-centered cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6-coordinate and has a local octahedral geometry.

Which is more covalent NaCl or CsCl?

If size of Na is smaller than that of Cs, then according to Fajan’s rule, Na should polarise Chlorine more and therefore, NaCl must have more covalent character than CsCl (and higher covalent character means low lattice energy).

What is the crystal structure of NaCl?

Why CsCl is more stable than NaCl?

CsCl is more stable than NaCl. This is because higher the coordination number, greater are the forces of attraction between the cations and anions in the close-packed arrangement. As CsCl has co-ordination number of 8:8 while NaCl has a coordination number of 6 :6 , therefore, CsCl is more stable.

Is ZnS FCC or BCC?

Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS can be found. Summary: Zinc blend is a compound that comes in two forms: sphalerite and wurtzite….Introduction.

Which is more stable NaCl or CsCl?

Is ZNS FCC or BCC?

What is the basis of NaCl?

NaCl, Sodium Chloride, Salt Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion.

How is the structure of CSCL similar to NaCl?

The structure of CsCl can be seen as two interpenetrating cubes, one of Cs+ and one of Cl-. The ions are not touching one another. Touching would cause repulsion between the anion and cation. Some may mistake the structure type of CsCl with NaCl, but really the two are different.

What kind of lattice does CSCL crystallize in?

CsCl crystallize in a primitive cubic lattice which means the cubic unit cell has nodes only at its corners. The structure of CsCl can be seen as two interpenetrating cubes, one of Cs+ and one of Cl-. The ions are not touching one another. Touching would cause repulsion between the anion and cation.

Where are the ions located in a CsCl crystal?

(more)Loading…. CsCl has a cubic structure that consists of an infinite chain of ions. The Cs (or Cl) ions sit at the eight corners of the cube and the Cl (or Cs) sit at the center of the cube (thus it is NOT a body-centered lattice since that requires the SAME ion to occupy the edges and center).
