Draw one coordination isomer and one linkage isomer of the following complex. Alright, so here we have our coordination complex. If we want to draw a coordination isomer, that means we have to substitute a counter ion for a ligand that's attached to the metal. Here we could do that. We still have our platinum. Here it would still be connected to the ammonias and it's the thiocyanate ion that's negatively charged, like the bromide counter ion that's negatively charged.
So I would just switch out the final cyanide or thiocyanate anion and bring in the bromide and then your file signing ion is on the outside. This will represent a coordination isomer for our linkage isomer. The ammonias are still there and what we're doing here. Remember, thiocyanate has resonance involved. Here we show the sulfur directly connecting to the metal cation, what I could easily have the nitrogen directly connecting to it instead, and the bromide ion would still be on the outside as a counter ion.
So this here would represent a linkage isomer right? So these are examples of a coordination isomer and a linkage isomer based on the original coordination complex given.
