description |
Supramolecular polygons and polyhedral have many novel applications such as nanoreactors, molecular nanosensors, Host-guest chemistry, among others. In this work is presented the synthesis, characterization and comparison of supramolecular polygons selfassembled between complexes of type [M(dppe)(TOF)2], which have metal centers in the same group (M = Ni, Pd and Pt) and the organic molecule 4,4'-bipyridine. Analyses by UV -Vis , FT -IR , FT -Raman , 1H- 31P -, 1H COSY-and 19F- NMR, showed that the nickelcontaining complex only formed a square, while the palladium- and platinum-containing complexes formed a triangle–square equilibrium.In addition, PM6 calculations for the supramolecular complexes, considering cationic and neutral systems in the gas phase and in solution, were performed. These results reveal that for the three metals, regardless of the environment, the formation of squares is energetically favored over the formation of triangles. Furthermore, it is observed that the Ni centers favor more the formation of squares, whereas the Pt centers favor it less. These theoretical trends are in good agreement with the experimental results. |

En este trabajo se presenta la síntesis, caracterización y comparación de polígonos supramoleculares autoensamblados entre complejos de tipo [M(dppe)(TOF)2], con centros metálicos de un mismo grupo (M = Ni, Pd y Pt)y la molécula orgánica 4,4'-bipiridina. Los análisis realizados por UV-Vis, FT-IR, FT-Raman, 1H-, 31P-, 1H COSY- y19F-RMN, demostraron que el complejo que contiene níquel formo únicamente un cuadrado, mientras que los complejos que contienen paladio y platino presentaron un equilibrio triangulo-cuadrado.Además se realizaron cálculos PM6 para los complejos supramoleculares, considerando sistemas catiónicos y neutros, tanto en fase gaseosa como en disolución. Los resultados muestran que para los tres metales, sin importar el medio, se ve favorecida energéticamente la formación de cuadrados en comparación con la formación de triángulos. Además, se observa que los centros de Ni favorecen más la formación de cuadrados, mientras que los centros de Pd la favorecen menos. Las tendencias teóricas se encuentran en concordancia con los resultados experimentales.application/pdfspaUniversidad Nacional de Colombiahttp://revistas.unal.edu.co/index.php/rcolquim/article/view/45917Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de QuímicaRevista Colombiana de QuímicaRevista Colombiana de Química; Vol. 42, núm. 3 (2013): Versión preliminar; 413-429 2357-3791 0120-2804Torres, Paulo C. and Moncada, Félix and Duarte Ruiz, Álvaro (2013) Experimental and theoretical studies of ni, pd and pt supramolecular polygons, self-assembled with 4,4´-bipyridine.
