Question

When silver nitrate is reacted with the molecular base ortho-phenanthroline, colorless crystals form that contain the transition-metal complex shown below.

Part A)

What is the coordination geometry of silver in this complex?

Part B)

Assuming no oxidation or reduction occurs during the reaction, what is charge of the complex shown here?

Express your answer as a signed integer.

Part C)

Do you expect any nitrate ions will be present in the crystal?

Part D)

Choose the formula for the compound that forms in this reaction.

Choose the formula for the compound that forms in this reaction.

Square planar Octahedral Bent Tetrahedral

Explanation / Answer

The coordination geometry of silver in this complex is Tetrahedral.

The charge of the complex shown here is +1.

As the charge of the complex is +1 there must be one nitrate anion (NO3-) to balance the positive charge.

Formula for the compound that forms in this reaction is [Ag(o-phen)2]NO3.
