The reaction of [Ru(eta(6)-p-cymene)Cl-2](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) (L-4) and [NH4][PF6] in ethanol solution forms the [RuCl(eta(6)-p-cymene)kappa(2)-L-4}][PF6] complexes. Similar Os(II) complexes are obtained starting with [Os(eta(6)-p-cymene) Cl-2](2). Treatment of [RuCl(eta(6)-p-cymene)kappa(2)-L-4}][PF6] with a further 0.5 mol equivalents of [Ru(eta(6)-pcymene) Cl-2](2) or reaction of [Ru(eta(6)-p-cymene) Cl-2](2) directly with 1.0 mol equivalent of L-4 forms the homobimetalllic [RuCl(eta(6)-p-cymene)} 2kappa(2) k'(2)-L-4}][PF6](2). Reaction of [OsCl(eta(6)-p-cymene)-kappa(2)-C (CH2SeMe)(4)}][PF6] with [Ru(eta(6)-p-cymene) Cl-2](4) or [PtCl2(MeCN)(2)] affords the heterobimetallic [OsCl(eta(6)p- cymene)}RuCl(eta(6)-p-cymene)}kappa(2) k'(2)-C(CH2SeMe)(4)}][PF6](2) and [OsCl(eta(6)-p-cymene)}PtCl2}kappa(2)k'(2)-C (CH2SeMe)(4)}][PF6] respectively. The complexes have been characterised by multinuclear NMR and IR spectroscopy and X-ray crystallography. (C) 2010 Elsevier B. V. All rights reserved.
