Abstract

The reaction of [RuCl2(PPh3)(3)] with tripodal Group 16 donor ligands L-3 {MeC(CH2EMe)(3) (E=Se or Te) and MeC(CH2TePh)(3)} gave [RuCl2(PPh3)L-3] complexes which have been characterised by elemental analysis, IR and NMR spectroscopy and ES+ mass spectrometry. The structure of [RuCl2(PPh3){MeC(CH2SeMe)(3)}] reveals a distorted octahedral geometry with a facially co-ordinated triselenoether. The reaction of [RuCl2(dmso)(4)] with L-3 gave [RuCl2(dmso)L-3] which have similarly been characterised, including a crystal structure of [RuCl2(dmso){MeC(CH2SeMe)(3)}], which is fac-octahedral with S-bonded dmso. The [RuCl2(dmso)L-3] species react with Ag[CF3SO3] in MeCN to produce [Ru(MeCN)(3)L-3](2+) {L-3=MeC(CH2SeMe)(3) or MeC(CH2TePh)(3)}. The MeCN is labile and readily replaced by a second tridentate ligand to give mixed tripod ligand complexes including [Ru{MeC(CH2SMe)(3)}{MeC(CH2SeMe)(3)}][CF3SO3](2) and [Ru{MeC(CH2SeMe)(3)}{MeC(CH2TePh)(3)}][CF3SO3](2). Attempts to generate hydride species by reaction of [Ru(MeCN)(3)L-3](2+) with NaBH4 in ethanol bring about decomposition.
