The monocarbon carborane [Cs][nido-7-CB(10)H(13)] reacts with the 16-electron [RuCl(2)(PPh(3))(3)] in a solution of benzene/methanol in the presence of N,N,N',N'-tetramethylnaphthalene-1,8-diamine as the base to give a series of 12-vertex monocarbon arene-biruthenacarborane complexes of two types: [closo-2-[7,11-exo-RuClPPh(3)(mu,eta(6)-C(6)H(5)PPh(2))]-7,11-(mu-H)(2)-2,1-RuCB(10)H(8)R] (5, R = H; 6, R = 6-MeO; 7, R = 3-MeO) and [closo-2-(eta(6)-C(6)H(6))-10,11,12-[exo-RuCl(PPh(3))(2)]-10,11,12-(mu-H)(3)-2,1-RuCB(10)H(7)R(1)] (8a, R(1) = 6-MeO; 8b, R(1) = 3-MeO, inseparable mixture of isomers) along with trace amounts of 10-vertex mononuclear hypercloso/isocloso-type complexes [2,2-(PPh(3))(2)-2-H-3,9-(MeO)(2)-2,1-RuCB(8)H(7)] (9) and [2,5-(Ph(3)P)-2-Cl-2-H-3,9-(MeO)(2)-2,1-RuCB(8)H(6)] (10). Binuclear ruthenacarborane clusters of both series were characterized by a combination of analytical and multinuclear NMR spectroscopic data and by single-crystal X-ray diffraction studies of three selected complexes, 6-8. In solution, isomers 8a,b have been shown to undergo the isomerization process through the scrambling of the exo-[RuCl(PPh(3))(2)] fragment about two adjacent triangular cage boron faces B(7)B(11)B(12) and B(8)B(9)B(12). 相似文献

It has been established by X-ray structural study that the bicluster cobalt -arene complex of diphenylmethane [6-PhCo4CO9]2CH2 and binuclear complex [6-PhCr(CO)3]2CH2 have ans-trans-s-trans conformation in their crystals.Translated fromIzvestiya Akademii Nauk.

Complex Ru3(μ-CO)2(CO)6{μ3-η1:η1:η4:η4-C4Ph2(CH=CHPh)2} containing an open triruthenium framework undergoes rearrangement to the Ru3-triangular Ru3(CO)8{μ3-η1:η1:η4:η2-C4Ph2(CH=CHPh)2) cluster when heated in refluxing hexane. Reactions of the latter complex with PPh3, P(OPri)3, and CO were studied. The structure of one of the reaction products, the Ru3(CO)8(PPh3{μ3-η1:η1:η4-C4Ph2(CH=CHPh)2} cluster, was established by X-ray structural analysis. 相似文献

As was shown by IR spectroscopy, the reaction of the three-mercury anticrown (o-C6F4Hg)3 (1) with the [H3BCN]ion in THF affords the complexes {[(o-C6F4Hg)3][H3BCN](5) and [(o-C6F4Hg)3]2[H3BCN](6). Complex 6 was isolated from solution in the analytically pure state. According to X-ray diffraction data, complex 6 has a double-decker sandwich structure, in which the borohydride group of the [H3BCN]? anion is bound to one anticrown molecule by three B-H-Hg bridges, whereas the cyanide group is cooperatively coordinated by three mercury centers of another molecule 1 through the nitrogen atom. The reaction of compound 1 with triethylamineborane Et3NBH3 in THF affords the 1: 1 complex ~[(o-C6F4Hg)3][Et3NBH3]~ (7). In this adduct, the binding of the aminoborane to the mercury anticrown is also accomplished by B-H-Hg bridges. The stability constants of complexes 5 and 6 in THF were determined. 相似文献

The structures of tetrafluoroborates of the secondary permethylmetallocenylmethyl cations [Cp*MC5Me4CHR]+ (Cp* = C5Me5; 1b: M = Ru, R = Ph; 1c: M = Os, R = C6F5) were established by X-ray diffraction analysis. The angles of inclination () of the C(1)—C(11) bond coordinated to the metal atom with respect to the plane of the C5Me4 ligand are 31.5° and 35.6°, and the M—C(11) distances are 2.506 and 2.401 in 1b,c, respectively. 相似文献

Chelate exo-nido-ruthenacarboranes exo-5,6,10-[RuCl(Ph2P(CH2)4PPh2)]-5,6,10-(μ-H)3-10-H-7,8-R,R′-nido-7,8-C2B9H6 (R, R′ = H, PhCH2) were synthesized by the direct method using the reaction of Cl2Ru(PPh3)(Ph2P(CH2)4PPh2) with [7,8-R,R′-nido-7,8-C2B9H10][K] in benzene. Unsubstituted exo-nido-ruthenacarborane (R, R′ = H) was used in situ for the synthesis of the dinuclear Ru-Cu exo-closo cluster of the formula exo-closo-(Ph3P)Cu(μ-H)Ru(Ph2P(CH2)4PPh2)(η5-C2B9H11). The isomerism of the complex and the crystal structure were studied by NMR spectroscopy and X-ray diffraction. The catalytic activity of the cluster in the atom transfer radical polymerization of methyl methacrylate was investigated. 相似文献

Rhodium and iridium complexes of a new ferrocene-derived bis(N-heterocyclic carbene) ligand, [M(cod){1,2-(MeNCHCHNCCH(2))(2)C(5)H(3)}Fe(C(5)H(5))]BF(4) (M = Rh, 8a; M = Ir, 8b; cod = 1,5-cyclooctadiene), were synthesized from the corresponding bis(imidazolium) salt 6. The molecular structure of 8a was determined by single-crystal X-ray diffraction. Complexes 8a and 8b smoothly react with CO with displacement of the chelating cod ligand to give the corresponding dicarbonyl derivatives 9a and 9b. 相似文献
