Deduce the structures of the following
compounds. This can be achieved by using the
molecular formula (which indicates the number of
ligands), the magnetic moments (which will provide
information about the number of unpaired electrons) and hence,
possible electron configuration. To do this,
consider and draw the crystal field diagrams for each of
the possible structures and use those factors to
decide which one it must be based on the number of
ligands and unpaired electrons.
