Abstract
Two porous mixed valent diruthenium(II,III)-dicarboxylate compounds have been prepared and characterized by spectroscopic methods, X-ray diffraction and thermogravimetry. Crystalline solids of [Ru 2(tere) 2Cl]·3.5H 2O (tere = terephthalate) and [Ru 2(adip) 2Cl]·1.5H 2O (adip = adipate) consist of extended chains in which polymeric layers of multiply metal–metal bonded [Ru 2] 5+ cores are bridged by dicarboxylate ligands in paddlewheel type geometries. Units of [Ru 2(dicarboxylate) 2] n + are linked by axial bridging chloride ions generating three-dimensional networks. The polymers loose non-bonded water molecules at low temperatures but do not undergo thermal decomposition below 280–300 °C. Both of compounds exhibit high BET surface areas, [Ru 2(tere) 2Cl]: 235 m 2 g −1 and [Ru 2(adip) 2Cl]: 281 m 2 g −1, and occlude similar numbers of mol of N 2 per mol of metal. The terephthalate ligand generated an organized structure with supermicropores (total pore size of 0.24 cm 3 g −1) while the adipate ligand led to a mesoporous structure (total pore sizes of 0.47 cm 3 g −1) for the corresponding diruthenium(II,III)-dicarboxylate polymers.
