(2006). From Simple Monopyridine Clusters [Mo6Br13 (Py-R)][n-Bu4N] and Hexapyridine Clusters [Mo6X8 (Py-R) 6][OSO2CF3] 4 (X= Br or I) to Cluster-Cored Organometallic Stars, Dendrons, and Dendrimers.

The orange pyridine-substituted clusters, whose pyridine protons are deshielded in 1H NMR (a practical tool for characterization), are air-stable and thermally stable with simple pyridines, light- and air-sensitive with organometallic pyridines, and air-fragile and thermally fragile with large dendronized pyridines.engMonopyridine clustersHexapyridine clustersCluster-cored organometallic starsDendronsDendrimers.Faculdade de Ciências Exatas e da Engenhariajournal article10.1021/ic051680f
