The structural behaviors of the phosphine ligands in the desired complexes during synthesis were monitored by 31P{1H}-NMR. The structure of complexes 1-3 described herein has been deduced from elemental analyses, infrared, FAB-MS and 1H-, 13C- and 31P-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 13C-, 29Si- and 31P-NMR spectroscopy, infrared spectroscopy and EXAFS.<\/jats:p>","DOI":"10.3390\/molecules15053618","type":"journal-article","created":{"date-parts":[[2010,5,17]],"date-time":"2010-05-17T11:13:22Z","timestamp":1274094802000},"page":"3618-3633","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Synthesis and Spectrosopic Identification of Hybrid 3-(Triethoxysilyl)propylamine Phosphine Ruthenium(II) Complexes"],"prefix":"10.3390","volume":"15","author":[{"given":"Ismail","family":"Warad","sequence":"first","affiliation":[{"name":"Department of Chemistry, King Saud University, P.
