What is a normal spinal structure in solid state chemistry?

[Kitrak]

In solid state chemistry, what's a normal spinal structure? I came across a question about it and I couldn't find any credible answers.

Spinal?

Please elaborate, your question (even assuming I guess correctly what it is about) is rather cryptic.

I think you mean 'spinel.' Here's a description of normal and inverse spinels:

And here's a site with examples (see left-hand menu for examples of different crystal structures:

TeethWhitener, you're right. The book printed it wrong I guess. So the +2 cation occupies 1/8^th of the tetrahedral voids and the +3 cation occupies half of the octahedral voids?

*spinel
Sorry about the spelling mistake :P
The original question was about the lattice system of the anions in a normal spinel structure.
