drawing coordination compounds

Postby Sophie Krylova 2J » Thu Nov 30, 2017 9:43 pm

When we draw a coordination compound, in which the ligand is charged, do we indicate the charge on the ligand in the lewis structure?

I think if the total molecule has a charge, you should bracket it and indicate the charge like you would with any other Lewis structure.

But what if individual ligands have charge, like CN- or SO4-2? So when you draw the lewis structure of what is inside the brackets, would you add the charges on those ligands?

I don't think you have to indicate the charge on each individual ligand in a coordination compound, as it would be noted in the overall charge at the end regardless.

I believe the most important part of drawing a coordination compound is known what is the central atom and what the various ligands are. This is the concept that was most stressed in lecture.

I don't believe it is necessary to draw the charge but rather the overall charge on the compound as a whole.
