Body-centered-cubic # and types of holes?

  1. In the Body-centered-cubic (BCC) unit cell which types of holes (interstices) are there? (tetrahedral, octahedral, or cubic) How many of each type?

    What do you think? What would your answers be and why?

  4. They look like octahedral holes to me, but online literature says tetrahedral OR cubic OR tetrahedral and octahedral.

    Nuts, my image source went away. I got it from Google Images, so here's another: unit.gif


    You might try browsing through some Google Images for Body Centered Cubic, to see if the images help to show the shape of the spaces better...

    Can you post the links to the conflicting online sources? Thanks.
