Coordination number of 3D close packing
As @Poutnik said, the packing is infinite, so there are no corner spheres.
Consider it this way-
- Also note that each sphere is in contact with one sphere on the layer just above it and one sphere on the layer just below it. A total of two additional spheres thus.
Hence the co-ordination number is 4+2=6.

Can anyone explain me that how the coordination number of corner sphere of this 3-D packing is 6 ? it should be 3
Poutnik almost 2 yearsThe 3D packing is considered infinite, so there is no corner sphere.
Raghavendra Singh almost 2 yearsPlease note that spheres diagonal to each other are NOT considered adjacent. Also, we have only taken into account Cubic close packing here...
