Preparation and x-ray crystal structure analysis of the hydroxo-bridged, dinuclear (.pi.-arene)ruthenium(II) cation in [Ru2(.eta.6-C6H6)2(.mu.-OH)3]Cl.3H2O

Layered compounds based on molybdenum disulfide and ruthenium arene complexes

“…17 We can therefore suggest that proceeds in both acidic and basic media. The two resulting weakly basic conditions used for the synthesis of 2-4 may also intercalates (compounds 1 and 2) exhibit nearly identical be favourable for the formation of dimeric complexes which interlayer distance expansions (Dc).…”

Organometallic Hydroxides of Transition Elements

“…However, it is limited. The reaction of [Ru 2 (η 6 -C 6 H 6 )Cl 2 ] 2 with TlOPh (1:3 molar ratio) leads to the triple-phenoxo-bridged product [Ru 2 (η 6 -C 6 H 6 ) 2 ( μ -OPh) 3 ] + in 86% yield . This compound on reaction with water at room temperature gives [Ru 2 (η 6 -C 6 H 6 ) 2 ( μ -OH) 3 ] + in essentially quantitative yield.…”

“…This compound on reaction with water at room temperature gives [Ru 2 (η 6 -C 6 H 6 ) 2 ( μ -OH) 3 ] + in essentially quantitative yield. The crystal structure of the chloride salt [Ru 2 (η 6 -C 6 H 6 ) 2 ( μ -OH) 3 ]Cl·3H 2 O showed the cation to be a triply bridged hydroxo complex having essentially D 3 h symmetry . It was speculated that the very basic medium of the original synthesis resulted in nucleation of the dimer to give the tetranuclear product.…”

Structurally Characterized Organometallic Hydroxo Complexes of the f- and d-Block Metals

“…"The final structurally characterized Ni complex is Ni3(CH2C6H4Me)4(PMe3)2(M3-OH)2 which originally was obtained as a minor side product during the work up of reactions between NiCl2(PMe3)2 and Mg(CH2CeH4-Me)(Cl). Subsequently it was prepared in70-80% yields by98 B. Palladium and Platinum A Pt complex, (dppe)PtMe(OH), whose Pt-0 bond distance is 202.5(8) pm has been mentioned in a review article, without details.2 [(C6Fs)2Pd(M2-OH)2Pd(C6Fs)2]2-can be prepared by a route analogous to that for [(CeFs^NiO^-OH^Ni-(C6F6)2]2-:100 2cis-(C6F5)2Pd(NCPh)2 + 2Bu4NOH -*• [But4N]2(C6F5)2Pd(M2-OH)2Pd(C6F5)2with platinum this method fails as coordinated benzonitrile undergoes nucleophilic attack by hydroxide. However, the bis(M2-OH) platinum complex has been obtained by chloride metathesis:101[Bu4N]2[(C6X5)2Pt(M2-Cl)2Pt(C6X5)2] + 2Bu4NOH -[Bu4N]2[(C6X5)2Pt(M2-OH)2Pt(C6X5)2] + 2Bu4NC1 X = F or ClAll three [B^NmCeFs^MG^-OH^M^Fsh] compounds (M = Ni102, Pd100, Pt101) are isomorphous, with square-planar metals forming a planar M2O2 ring.…”
