Inorganic Chemistry – Structure and Bonding
For discussion in the week of November 1, 2021
1. Cobalt fluoride crystallizes in a closet packed array of fluoride ions with the cobalt ions
filling one-half of the octahedral holes. What is the formula of this compound?
2. The compounds Na2O, CdS, and ZrI4 all can be described as cubic closest packed
anions with the cations in tetrahedral holes. What fraction of the tetrahedral holes is
occupied in each case?
3. The unit cell for an oxide of copper is shown below. Use the figure to determine the
formula of this compound.
4. Complete the table below by determining if following compounds obey the radius
ratio rule.
