Resumen
En esta unidad de investigación se describirá detalladamente el procedimiento de la síntesis, el análisis y la caracterización de los compuestos [(N^N)Re(CO)3(O-OCOCH3)] ((N^N)= 1,10-fenantrolina (phen) o 3,6-bis(1H-pirazol-1-il)piridazine (bppdz)) preparado por reacción directa a partir del bromuro de renio(I) tricarbonildiimina, [(N^N)Re(CO)3Br] con ácido acético (CH3COOH) para la formación del [(N^N)Re(O-OCOCH3)(CO)3] Posteriormente se caracterizó el complejo [(N^N)Re(CO)3(O-OCOCH3)]mediante análisis elemental, espectroscopia infrarroja, difracción de rayos-X en monocristal. Se muestra que la especia mono-metálica que contiene ReI unido a tres grupos carbonilos en conformación facial y con dos posiciones ocupadas por un ligando bidentado provenientes del respectivo quelato diimina, mostrándose en la siguiente figura 1 el respectivo complejo sintetizado (Figura 2 para (N^N)= 1,10-fenantrolina).
In this research unit the synthesis procedure, the analysis and the characterization of the compounds [(N^N)Re(CO)3(O-OCOCH3)] ((N^N) = 1,10-phenanthroline (phen) and 3,6-bis(1H-pyrazol-1-yl) pyridazine (bppdz)) prepared by direct reaction of rhenium(I) tricarbonyl diimine bromide, [(N^N)Re(CO)3Br] with acetic acid (CH3COOH) which leads to the formation of [(N^N)Re(O-OOCCH3)(CO)3],Subsequently, the complexes [(N^N)Re(CO)3(O-OCOCH3)] were characterized by elemental analysis, infrared spectroscopy and X-ray single-crystal diffraction. It is show that the mono-metallic species containing ReIlinked to three carbonyl groups in facial conformation, with two positions occupied by a bidentate ligand from the respective diimine chelate, showing in the following figure 1 the respective synthesized complex (Figure 2 for (N^N)= 1,10-phenanthroline).
