Is NaCl trigonal?

The NaCl structure can be described a face-centered cubic lattice with all of the octahedral holes filled. The cations are in octahedral coordination, so each cation is coordinated to six anions. The anions are also coordinated to six cations, but they occupy trigonal prismatic sites.

What is the structure of NaCl BCC or FCC?

NaCl is a FCC unit cell which has four cations and four anions. This can be shown by counting the number of ions and multiplying them in relation to their position.

Is NaCl tetrahedral?

The NaCl structure is a good example of the latter. One octahedral and one tetrahedral site in a face-centered cubic unit cell. Each cell contains four packing atoms (gray), four octahedral sites (pink), and eight tetrahedral sites (blue). Crystal structure of NaCl.

What is Z for NaCl?

Like, for NaCl which is in fcc- Z value is 4 but according to its hexagonal close packing structure its coordination number is 6.

What is NaCl en of the 2nd atom?

There are 2 atoms in NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. For Na it is 11 and for Cl it is 17. Hope this helps!

Is NaCl a CCP?

In NaCl structure, Na+ ions occupy octahedral holes and Cl− ions occupy ccp.

Is NaCl tetrahedral or octahedral?

The NaCl structure is a good example of the latter. One octahedral and one tetrahedral site in a face-centered cubic unit cell. Each cell contains four packing atoms (gray), four octahedral sites (pink), and eight tetrahedral sites (blue).

Does NaCl have tetrahedral voids?

The number of tetrahedral voids is twice the number of atoms per unit cell, and number of octahedral voids is equal to the number of atoms per unit cell. Hence, NaCl contains 4 × 2 = 8 tetrahedral voids and 4 octahedral voids.

Is NaCl a crystalline?

Sodium chloride has a crystalline structure made up of Na^ + and Cl^ – ions.
