Crystal lattice structure

    what is this

    answer choices:
    a. Primitive cubic with an octahedral hole
    b. Body centered cubic with an octahedral hole
    c. Face centered cubic with an octahedral hole
    d. None of the above
    e. Not enough information to determine

    We didn't talk about this in class, and this was a question on a test...this picture is in our textbook, but not in reference to what it is. I think it was something along the lines of "determine the chemical formula"...but anyway, I am at a total loss here.

    nb c; Face centered cubic with an octahedral hole, is correct

    Sigh. It is in a wrong forum (should be in homework section), OP didn't show any effort to answer the problem (required by the rules), and the only other post is giving the final answer (instead of guiding the OP to an answer). I should warn you both and delete the thread. Please read the forum rules.

    What is the precise question?

    maybe, what is the Crystal lattice structure

    Well then, there are 14 different crystal lattices (the Bravais lattices) and none of them has a hole, even less an octahedral one.
