Question:

What is the two dimensional coordination number of a molecule in square close packed layer?

Answer:

Square Close Packing: In this type, the spheres are packed in such a way that the centres of all of them are in straight line. This means that the different rows have horizontal as well as vertical alignment. Since each sphere is in contact with four other spheres in the same plane, this packing is called square close packing.

Coordination Number: The number of spheres which are touching a given sphere is called the coordination number. In square close-packed layer, a molecule is in contact with four of its neighbours. Therefore, the two dimensional coordination number of a molecule in square close-packed layer is 4.
