A green solid has the empirical formula FeBr3 5NH3 H₂O. Upon reaction with an excess of aqueous AgNO3 it is found that 1 mole of the solid precipitates 3 moles of AgBr. Heating the green solid leads to loss of 1 mole of H₂O to yield a blue solid with the same ratio of Fe:Br:NH3 as found in the green solid. The reaction of 1 mole of the blue solid with excess of aqueous AgNO3 produces 2 moles of AgBr. Draw and name the octahedral green and blue complexes.

A green solid has the empirical formula FeBr3·5NH3 H₂O. Upon reaction with
an excess of aqueous AgNO3 it is found that 1 mole of the solid precipitates 3
moles of AgBr. Heating the green solid leads to loss of 1 mole of H₂O to yield
a blue solid with the same ratio of Fe:Br:NH3 as found in the green solid.
The reaction of 1 mole of the blue solid with excess of aqueous AgNO3
produces 2 moles of AgBr. Draw and name the octahedral green and blue
complexes.
An octahedral complex having the formula [M(dien)(NH3)(OH₂)F] has a total
of 15 isomers. In the sum formula "dien" represents the tridentate
diethylenetriamine ligand, which can adopt meridional or facial coordination
modes. Draw structures of 8 possible isomers, clearly showing any pairs of
enantiomers. The tridentante ligand may be abbreviated as below for
simplicity.
