Velmurugan2 2CAS in Crystallography and Biophysics, University of Madras, Tamilnadu, India E-mail: srini771@gmail.com, shirai2011@gmail.com Received April, 18, 2014 1Department of Chemistry, Avinashilingam University for Women, Tamilnadu, India E-mail: sriadit.gowrisuresh@gmail.com Revised — May, 23, 2014 The title complex is synthesized and analyzed using single crystal X-ray diffraction studies. <...> The asymmetric unit [RuCl3(CO)(PPh3)2] of the title complex contains one half of the molecule. <...> The molecular structure is stabilized by C3—H3…Cl1 and C9—H9…Cl2 intramolecular halogen interactions which result in two S(6) ring motifs. <...> The crystal packing features are the C—H…Cg1 interactions, where Cg1 is the center of gravity of the phenyl ring (C14—C19). <...> No classical hydrogen bond is found in the complex. <...> Organometallic complexes with bonds that have characters in-between ionic and covalent are very important in industry since they are relatively stable in solutions and relatively ionic to undergo reactions. <...> This is the case of complexes having CO as one of their ligands [M=C=O M+C—O–]. <...> Phosphines are used as ligands for many metal complexes. <...> The most popular phosphine ligand used is triphenyl phosphine: a shelf-stable solid that relatively slowly undergoes oxidation in air. <...> Unlike most metal ammine complexes, metal phosphine complexes tend to be lipophilic, displaying good solubility in organic solvents. <...> Because of these two features, metal phosphine complexes are important in homogeneous catalysis [ 1 ]. <...> Being bonded to the Ru(III) metal atom in the complexes, the ligands such as triphenyl phosphine, carbonyl, and chloride have characteristic biological activities and they have extensively been studied. <...> Phosphine with the strongest acidity is trifluorophosphine (PF3); its acidity approaches that of the carbonyl ligand [ 2 ]. <...> Based on the views and approaches to the complexes with triphenyl phosphine, carbonyl, and chloride as ligands, we herein investigate the crystal structure of a novel Ru(III) complex <...>
