Welcome to our blog!

Here we could explain to you what are the coordination compounds formed in the experiment of Trigger 3(Problem 1), why does this happened, rules and steps in naming coordination compounds and etc. Try to relax yourself and explore what we are doing!

Question 2

Explain why the difference in color occured in experiment 1. Give other examples that are caused by the same reason in coordination compounds.

Answer: It is depends on the particular elements, oxidation state and the ligand bound to the metal. Besides, it is also because of the linkage isomerism. This arises when a particular ligand is capable of coordinating to a metal in two different ways. Two coordinations:
  1. Nitro isomer - coordinate by N atom ( yellow )
  2. Nitrito isomer - coordinate by O atom ( red )
Other examples that are caused by the same reason in coordination compounds are:
Ion complex: [Pd(NH3)2(ONO)2]
This complex also has linkage isomerism.
Formulas: [Pd(NH3)2(ONO)2], [Pd(NH3)2(NO2)2]
