5. A student measures the magnetic moment of NiCl 42 - and obtains a value of \( 3.2 \mu \mathrm{~B} \). A value of \( 0.0 \mu \mathrm{~B} \) is measured for \( \mathrm{Ni}(\mathrm{CN}) 42 \) - . What do these values tell you about the geometry for the compounds? Show/explain all work. (Hint: compounds with a value of zero for magnetic moment are diamagnetic; non-zero measurements would indicate paramagnetism.)

Step 1
- A value of \(0.0 \mu_B\) indicates the compound is diamagnetic, meaning all electrons are paired. - A non-zero value, such as \(3.2 \mu_B\), indicates the compound is paramagnetic, meaning there are unpaired electrons. Show more…

Questions: 1) What physical indications, other than magnetic moment, might lead one to conclude that a metal-metal bond is present? 2) Even when the magnetic susceptibility seems to indicate that a metal-metal bond is present, the low magnetic susceptibility might be due to other reasons. Discuss this point. 3) One of the largest classes of metal-metal bonded compounds are the metal carbonyl clusters. Discuss the bonding in two such members of this class. 4) Metal clusters are under active investigation as "mimics" to bulk metals in catalysis. Perform a literature search and discuss several examples of metal clusters that were studied in this manner.

The $\left[\mathrm{Ni}(\mathrm{CN})_{4}\right]^{2-}$ ion, which has a square-planar geometry, is diamagnetic, whereas the $\left[\mathrm{NiCl}_{4}\right]^{2-}$ ion, which has a tetrahedral geometry, is paramagnetic. Show the crystal field splitting diagrams for those two complexes.
Use crystal-field theory to explain why some $\mathrm{Co}^{3+}$ octahedral complexes are diamagnetic and others are paramagnetic.
