dc.description.abstractTheoctahedralmolybdenumcluster[n-Bu4N]2[Mo6Br8(CF3SO3)6]undergoessubstitutionofallsixterminaltriflateligands withtheorganometallicpyridineligands[RuCp(PPh3)2(g1-C2-4-pyridinyl)],1,and1-ferrocenyl-2-(4-pyridinyl)acetylene,5,to give the new light and air sensitive hexa-functionalized Mo6 clusters 4 and 7 respectively, and with the dendronic phenolate ligand p-NaO–C6H4C{CH2CH2CH2Si(Me)2Fc}3, 8, to give the air-sensitive Mo6-cluster-cored octadecylferrocenyl dendrimer 9 that discloses a single CV wave in CH2Cl2 and recognizes the biologically important adenosyl triphosphate di-anion (ATP2-). The organometallic pyridines 1 and 5 were also coordinated toAg+ to give the new trinuclearAgRu2 andAgFc2 cationic complexes 2 and 6 respectively for comparison of the structures and electronic delocalization with those of the clusters.pt_PT
dc.description.abstractL’agrégat octaédrique [n-Bu4N]2[Mo6Br8(CF3SO3)6] subit la substitution des six coordinats triflates terminaux avec les ligandspyridiniquesorganométalliques[RuCp(PPh3)2(g1-C2-4-pyridinyl)],1,et1-ferrocenyl-2-(4-pyridinyl)acetylene,5,pour donner de nouveaux agrégats hexamolybdène hexafonctionnels 4 et 7, respectivement. Avec le phénate dendronique p-NaO– C6H4C{CH2CH2CH2Si(Me)2Fc}3,8, le dendrimère hexamolybdène octadécylferrocényle9est obtenu. Ce composé donne une seule vague en voltammétrie cyclique dans CH2Cl2 et reconnaît le dianion de l’ATP, dont l’importance est connue en biologie.
