Tesis doctoral de Rodr\u00edguez Castro Antonio M. <\/strong><\/h2>\n

Los compuestos de coordinaci\u00f3n con ligandos dadores de azufre pueden tener aplicaciones en distintos campos de la medicina y de la industria. adem\u00e1s, sirve como modelos para una mejor comprensi\u00f3n de la estructura y funcionamiento de metaloprote\u00ednas. dada la alt\u00edsima tendencia del azufre a establecer puentes entre \u00e1tomos met\u00e1licos, es muy frecuente la obtenci\u00f3n de compuestos polim\u00e9ricos o, al menos, de altas nuclereadidades que, generalmente, son bastante insolubles, lo que dificulta su caracterizaci\u00f3n estructural. los procedimientos para frenar esta tendencia a la polimerizaci\u00f3n son, entre otros, el uso de ligandos con otros \u00e1tomos dadores adem\u00e1s de azufre, adici\u00f3n de otros coligandos que saturen coordinativamente al metal y tambi\u00e9n el uso de ligandos con impedimentos est\u00e9ricos importantes, de forma que, en este caso, la obstaculizaci\u00f3n es debida a motivos f\u00edsicos. en este caso se escogieron ligandos pirimidin-2-tionato, que adem\u00e1s del \u00e1tomo de azufre, son dadores de nitr\u00f3geno. Se emplearon adem\u00e1s distintos coligandos nitrogenados y fosforados. en primer lugar se sintetizaron las pirimidin-2-tionas precursoras de los ligandos ani\u00f3nicos. La s\u00edntesis dependi\u00f3 de los reactivos precursores utiliz\u00e1ndose condensaciones entre dicetonas y tiourea en medio \u00e1cido o bien, carbonilos alfa-beta insaturados con tiourea en medio b\u00e1sico. La caracterizaci\u00f3n de estos compuestos se realiz\u00f3 por los m\u00e9todos espectrosc\u00f3picos habituales. las s\u00edntesis de los complejos simples se realizaron todas ellas utilizando un procedimiento electroqu\u00edmico. El metal correspondiente es el \u00e1nodo de una celda electroqu\u00edmica, mientras que el c\u00e1todo es un alambre de platino. ambos electrodos se sumergen en una disoluci\u00f3n de la tiona correspondiente y se a\u00f1ade una m\u00ednima cantidad de perclorato de tetraetilamonio que hace las veces de electrolito. los complejos mixtos con bipy o phen fueron sintetizados usando el mismo procedimie<\/p>\n
