ackground: In the last ten years, Photodynamic Antimicrobial Chemotherapy (PACT) has emerged as a reliable option to threat several bacterial and fungal infections. Tris(N,Ndiimine) chromium(III) complexes are known for their potential as photosensitizers; however, synthesis is usually a very time consuming procedure. Results: With our novel methodology, [Cr(biim)3](NO3)3 was prepared in a few seconds as a powder and the yield of the reaction was improved compared with previously described synthesis, where obtaining crystals is complicated due to the acidity of the media. The precursors for the synthesis are also synthesized through fast and simple methods. Identification of intermediates and the final product was performed by melting point, infrared, UV-vis and NMR spectroscopy. Conclusions: This article describe a quick, easy and eco-friendly procedure to synthesize the [Cr(biim)3](NO3)3 employing microwave irradiation.
