High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

4-Dimethylaminopyridinium–4-nitrophenolate–4-nitrophenol (1/1/1)

Acta Crystallographica Section E Structure Reports Online, 2003
Within and between mol­ecules of the title compound, C7H11N2+·C6H5NO3−·C6H4NO3, there are C—H⋯O, C—H⋯N, O—H⋯O and N—H⋯O interactions, which generate rings of graph-set motifs S(5), R12(5), R12(6), R12(7) and R21(4). The supramolecular aggregation is completed by the presence of three different π–π interactions and short van der Waals contacts.
