In the last ten years, the Photodynamic Antimicrobial Chemotherapy (PACT) has emerged as a reliable option to threat several bacterial and fungal infections. Tris(N,N-diimine)chromium(III) complexes are known for its potential as photosensitizers, however, their synthesis is usually a very time consuming procedure. Results: With our novel methodology, [Cr(biim)3](NO3)3 is prepared in a few seconds as a powder and the yield of the reaction is improved compared with the synthesis previously described, where the obtaining of 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 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.
