- Mo6Br8-Cluster-cored organometallic stars and dendrimersPublication . Méry, Denise; Ornelas, Cátia; Daniel, Marie-Christine; Ruiz, Jaime; Rodrigues, João; Astruc, Didier; Cordier, Stéphane; Kirakci, Kaplan; Perrin, ChristianeTheoctahedralmolybdenumcluster[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.
