Ce mémoire de thèse est consacré au développement et à la caractérisation de nouveaux complexes homo- et hétéronucléaires de manganèse et de métaux alcalino-terreux dans le cadre de la modélisation du cluster inorganique Mn4CaO5 de l’OEC du photosystème II.De nouveaux ligands incluant un nombre variable de groupements pyridine-carboxylates basés sur les architectures tris-(2-picolyl)amine et bis-(2-picolyl)ethylamine ont été synthétisés. Ces ligands ont permis d’isoler de nouveaux complexes homonucléaires avec Ca2+ et Sr2+ et ainsi que des complexes hétéronucléaires MnII–Ca. L’analyse par spectroscopie XAS sur le calcium de certaines de ces espèces (parmi d’autres modèles) a permis de calibrer cette technique et ainsi montrer que le XAS pou...
