What is the coordination number of NaCl structure?

In NaCl crystal, each sodium ion is surrounded by 6 chloride ions and each chloride ion is surrounded by 6 sodium ions. So, the coordination number of NaCl as per definition will be 6:6.

How do you find the coordination number of a lattice?

It’s more difficult to determine chemical bonding in solid-state crystals, so the coordination number in crystals is found by counting the number of neighboring atoms. Most commonly, the coordination number looks at an atom in the interior of a lattice, with neighbors extending in all directions.

What lattice structure does NaCl commonly adopt?

The NaCl structure can be described a face-centered cubic lattice with all of the octahedral holes filled. What if we start with a hexagonal-close packed lattice rather than a face-centered cubic lattice? Nickel arsenide crystal structure. The Ni6As trigonal prisms are shaded gray.

What is the coordination number of NaCl and CsCl?

CsCl is a BCC type arrangement, where each Cs⁺ atom is in contact with 8 Cl⁻ ions, hence the coordination number in CsCl is 8. In NaCl, each Na⁺ occupies the octahedral voids, and 6 Na⁺ ions surround one Cl⁻ ion, so coordination number in NaCl is 6.

Are there 6 or 8 coordination numbers in NaCl?

However, as shown in the figure below, the coordination numbers are not 6 as in NaCl. The center ion is the Cs + ion and is surrounded by the eight Cl − ions at the corners of the cube. Each Cl − ion is also surrounded by eight Cs + ions. The coordination numbers in this type of crystal are both 8.

What is the type of lattice structure of NaCl?

The feedback you provide will help us show you more relevant content in the future. Simply put, sodium chloride has a simple cubic lattice structure. Imagine a set of cubes with alternating Na and Cl ions at the corners, and that’s NaCl.

What is the coordination number of n ac L?

In N aC l, each N a+ ion is surrounded by 6 C l− ions and each C l− ions is surrounded by 6 N a+ ions. Thus, the coordination number of N a+ is 6 in N aC l. Was this answer helpful?

What is the coordination number of a chloride ion?

If you examine the figure below, you will see that there are six chloride ions immediately surrounding a single sodium ion. The coordination number of sodium is 6. Likewise, six sodium ions immediately surround each chloride ion, making the coordination number of chloride also equal to 6.
