abstract = {Quaternary alkyl 2-phenylpyridinium and 2-(2,4-difluorophenyl)pyridinium amines with iodide, hexafluorophosphate and bis(trifluoromethylsulfonyl)imide anions have been fully characterized by H-1 NMR, FT-IR and MALDI mass spectroscopic methods and studied by quantum chemistry calculations. The compounds with bis(trifluoromethylsulfonyl)imide anion can be classified as ionic liquids, because they melt at room temperature. The quaternary amines with iodide and hexafluorophosphate anions are solid at 25 degrees C. The X-ray diffraction characterization of the 2-(2,4-difiuorophenyl)-1-methylphenylpyridinium hexafluorophosphate and 1-ethyl-2-(2,4-difluorophenyl)phenylpyridinium hexafluorophosphate show an extensive series of C-H center dot center dot center dot F, C-F center dot center dot center dot pi and P-F center dot center dot center dot pi it intermolecular interactions, which give rise to a supramolecular network. The relationship between the solid-state structures and the melting points is discussed by the evaluation of the thermal behavior based on experimental data from Differential Scanning Calorimetry (DSC) studies, and also using the analysis of the ion pairs binding energies. These new compounds based on phenylpyridine allow us to grow the diversity of ionic liquids and their crystalline salts, increasing the knowledge about the chemical and physical properties of these ionic species.},

abstract = {Gold and silver complexes containing the monophosphane 1-PPh2-2-Me-1,2-C2B10H10 with different coordination numbers (2, 3) have been synthesized: [M(7,8-(PPh2)(2)-C2B9H10)(1-PPh2-2-Me-C2B10H10)] (M = Ag, Au) and [Au-2(mu-1,n-C2B10H10)(1-PPh2-2-Me-C2B10H10)(2)] (n = 2, 12). Solid-state pyrolysis of [AuCl(1-PPh2-2-Me-C2B10H10)] and [Au-2(mu-1,12-C2B10H10)(1-PPh2-2-Me-C2B10H10)(2)] in air and of solutions of [AuCl(1-PPh2-2-Me-C2B10H10)] deposited on silicon and silica at 800 degrees C results in single-crystal Au, confirmed by diffraction and SEM-EDS. The morphology of the pyrolytic products depends on the thermolytic conditions, and different novel 3-D superstructures or microcrystals are possible. We also propose a mechanism for the thermal conversion of these precursors to structural crystalline and phase pure materials. The presence of the carborane monophosphane seems to originate quenching of the luminescence at room temperature in the complexes [Au-2(mu-1,n-C2B10H10)(1-PPh2-2-Me-C2B10H10)(2)], in comparison with other [Au-2(mu-1,n-C2B10H10)L-2] species (L = monophosphane).},
