The reaction of [Ru(η6-p-cymene)Cl2]2 with 2.0 mol equivalents of C(CH2SMe)4, C(CH2SeMe)4, 1,2,4,5-C6H2(CH2SMe)4 or 1,2,4,5-C6H2(CH2SeMe)4 (L4) and [NH4][PF6] in ethanol solution forms the [RuCl(η6-p-cymene){κ2-L4}][PF6] complexes. Similar Os(II) complexes are obtained starting with [Os(η6-p-cymene)Cl2]2. Treatment of [RuCl(η6-p-cymene){κ2-L4}][PF6] with a further 0.5 mol equivalents of [Ru(η6-p-cymene)Cl2]2 or reaction of [Ru(η6-p-cymene)Cl2]2 directly with 1.0 mol equivalent of L4 forms the homobimetalllic [{RuCl(η6-p-cymene)}2{κ2κ′2-L4}][PF6]2. Reaction of [OsCl(η6-p-cymene)-{κ2-C(CH2SeMe)4}][PF6] with [Ru(η6-p-cymene)Cl2]2 or [PtCl2(MeCN)2] affords the heterobimetallic [{OsCl(η6-p-cymene)}{RuCl(η6-p-cymene)}{κ2κ′2-C(CH2SeMe)4}][PF6]2 and [{OsCl(η6-p-cymene)}{PtCl2}{κ2κ′2-C(CH2SeMe)4}][PF6] respectively. The complexes have been characterised by multinuclear NMR and IR spectroscopy and X-ray crystallography. 相似文献

A range of complexes of the binucleating tetrathio- and tetraseleno-ether ligands, 1,2,4,5-C6H2(CH2EMe)4 (E = S, L3 or Se, L4) or C(CH2EMe)4 (E = S, L5 or Se, L6) and of bidentate analogues 1,2-C6H2(CH2EMe)2 (E = S, L1 or Se = L2) with molybdenum and tungsten carbonyls and manganese carbonyl chloride have been prepared, and characterised by IR and multinuclear NMR (1H, 13C{1H}, 77Se, 55Mn, 95Mo) spectroscopy and mass spectrometry. Crystal structures are reported for [Mo(CO)4(L2)], [Mo(CO)4(L3)], [Mo(CO)4(μ-L3)Mo(CO)4], [Mo(CO)4(L4)], [Mn(CO)3Cl(μ-L3)Mn(CO)3Cl], [Mo(CO)4(μ-L5)Mo(CO)4], [Mn(CO)3Cl(L5)] and two forms (containing meso and DL diastereoisomers) of [W(CO)4(L5)]. 相似文献
