Carbon tetrachloride has four polar covalent bonds. It is a tetrahedral molecule, so the charges are symmetrical. The \(\delta+\) part of the molecule (the carbon atom) is locked away at the ...

The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B cation occupy octahedral holes. It then follows that 1/8 of the tetrahedral holes ...
