Resumo

This work presents an approach that integrates the preparation of a coordination compound, potassium tris-(oxalato)ferrate(III), with its photochemical behavior and provides a possible application, the printing of a photograph using the cyanotype technique. Through this experiment, students can be taught several concepts that occur in a coordination chemistry course, including the thermodynamic aspects of forming a compound, its photochemistry, the detection of its photoproducts, and the observation of the formation of a new compound and the resulting intervalence band, which generates the blue print.
