title: Synthesis and spectrosopic identification of hybrid 3-(triethoxysilyl)propylamine phosphine ruthenium(II) complexes.
abstract: An investigation into the potential ruthenium(II) 1-3 complexes of type [RuCl(2)(P)(2)(N)(2)] using triphenylphosphine and 1,3-bis-diphenylphosphinepropane and 3-(triethoxysilyl)propylamine has been carried out at room temperature in dichloromethane under an inert atmosphere. The structural behaviors of the phosphine ligands in the desired complexes during synthesis were monitored by (31)P{(1)H}-NMR. The structure of complexes 1-3 described herein has been deduced from elemental analyses, infrared, FAB-MS and (1)H-, (13)C- and (31)P-NMR spectroscopy. Xerogels X1-X3 were synthesized by simple sol-gel process of complexes 1-3 using tetraethoxysilane as co-condensation agent in methanol/THF/water solution. Due to their lack of solubility, the structures of X1-X3 were determined by solid state (13)C-, (29)Si- and (31)P-NMR spectroscopy, infrared spectroscopy and EXAFS.
