Heterobimetallic Group 6-rhodium complexes III. (M = Mo, W; NN = phen or bpy) as P-donor in M-Rh complexes

A new synthetic route to heterobimetallic M-Rh (M = Mo or W) complexes has been explored.The procedure is the reaction of RhI complexes of the type 2> (diolefin = NBD or COD) with the complexes of monodentate dppm (NN = phen or bpy), which are potential phosphine ligands.The products obtained were studied by IR, 31P-NMR and 1H-NMR spectroscopies and formulated as (M = Mo or W; diolefin = NBD or COD; NN = phen or bpy) containing a M-Rh bond bridged by dppm and semibridged by CO.Keywords: Molybdenum; Tungsten; Dinuclear diphosphine complexes; Heterobimetallic complexes; Rhodium-Group 6 complexes; Diphenylphosphinemethane

Mono- and Bis-Bridged Ru-Rh Complexes. Preparation, Characterization, and Reactivity. X-ray Crystal Structure of RuRhH(Ph)(PhPCH2PPh2)(Ph2PCH2PPh2)(C8H12)*1/2PhMe and of RuHCl(Ph2PCH2PPh2)2*1/2PhMe

The reaction of RuCOD(dppm)2 (COD = cis,cis-1,5-cyclooctadiene, dppm = bis(diphenylphosphino)methane) with 2 affords Ru(CO)(COD)(dppm) and 2 at room temperature after ligand exchange.At 80 deg C two further products are obtained, Rh2Cl2(dppm)2 and RuRhCl(CO)3(dppm)2 (1), which is the main product if the reaction is performed under CO.A mechanism is proposed. 1 reacts with H2 to give RuRhH2Cl(CO)2(dppm)2 which can also be obtained from RuH2(dppm)2 and 2.The reaction of RuH2(dppm)2 with 2 leads to RuRhH2Cl(COD)(dppm)2 (3) which contains one bridging and one chelating dppm group. 3 does not react with C2H4, decomposes under H2, and reacts with CO to give 1 and with P(OMe)3 to give two isomers of RuHClP(OMe)3(dppm)2, 5 and 6, and RhH(POMe3)4.Similarly, the reaction of RuH2(dppm)2 with 2 produces RuIrH2Cl(COD)(dppm)2 (4) analogous to 3, but in this case some redistribution to RuHCl(dppm)2 is also observed.Finally, reduction of 3 with MeLi at 0 deg C leads to methane elimination and the formation of RuRhH(Ph)(PhPCH2PPh2)(dppm)(COD) (7) which contains a phosphido bridge between Ru and Rh and a trans hydrido phenyl environment for ruthenium. 7 reacts with CO to give RuRhH(Ph)(PhPCH2PPh2)(dppm)(CO)2 (8).Full spectroscopic characterization of the new complexes is described, viz., 1H, 13C, and 31P NMR and determination of the 103Rh resonance frequency.The crystal structures of RuHCl(dppm)2*1/2PhMe and of 7 are described.RuHCl(dppm)2*1/2PhMe: C2h5-P21/c; Z = 4; a = 10.138(2) Angstroem, b = 21.206(3) Angstroem, c = 22.066(3) Angstroem, β = 103.93(1) deg, V = 4604.4 Angstroem3, R = 0.046 for 2948 reflections with F02 > 3?(F02).RuRhHPh(PhPCH2PPh2) (COD)(dppm)*0.5PhMe: C2h5-P21/c; Z = 4; a = 15.985(3) Angstroem, b = 18.324(4) Angstroem, c = 19.496(4) Angstroem, β = 112.20(2) deg, V = 5287.2 Angstroem3, R = 0.034 for 4751 reflections with F02 > 4?(F02).

Binuclear rhodium complexes: Their chemistry with sulfur dioxide and the structure of [Rh2Cl2(μ-SO2)((C6H 5)2PCH2P(C6H5) 2)2]

The "A-frame" complex [Rh2(CO)2(μ-Cl)(DPM)2][B(C6H 5)4] (DPM = (C6H5)2PCH2P(C6H 5)2) undergoes a facile and reversible reaction with SO2 to yield [Rh2(CO)2(μ-Cl)(μ-SO2)(DPM) 2][B(C6H5)4]. Spectroscopic studies have shown that SO2 attack occurs directly at the bridging site of the "A-frame" complex. Treatment of a solution of the SO2 adduct with excess SO2 in the presence of chloride ion yields a second SO2 complex, [Rh2Cl2(μ-SO2)(DPM)2], the structure of which is reported. In the absence of chloride ion, formation of the second SO2 complex occurs in the presence of small amounts of [RhCl2(CO)2]- with the latter functioning as a chloride-transfer agent. Treatment of the second, SO2-bridged species with CO yields the complex [Rh2(CO)2(μ-CO)(μ-Cl)(DPM)2][Cl] which can then be readily converted in solution to the dicarbonyl species cis-[Rh2Cl2(CO)2(DPM)2]. The reaction of trans-[Rh2Cl2(CO)2(DPM)2] with SO2 has also been investigated and has been shown to occur by terminal SO2 attack, forcing the terminal carbonyl and chloro ligands on one Rh atom into the bridging positions. In solution this species then loses Cl- and rearranges to the complex [Rh2(CO)2(μ-Cl)(μ-SO2)(DPM) 2][Cl] which can yield [Rh2Cl2(μ-SO2)(DPM)2] by recoordination of Cl- and subsequent CO loss. The X-ray structural determination of [Rh2Cl2(μ-SO2)(DPM)2] shows this species to be a distorted "A-frame" complex with a symmetrically bridging SO2 ligand and terminal chloro ligands. The complex crystallizes in the space group C2h5-P21/c in a cell of dimensions a = 18.228 (1) A?, b = 13.526 (1) A?, c = 19.632 (2) A?, and β = 104.72 (1)° with Z = 4. On the basis of 5207 unique reflections, the structure was refined by full-matrix, least-squares techniques to agreement indices of R = 0.058 and Rw = 0.067. Some relevant metrical parameters are Rh-P(av) = 2.331 (9) A?, Rh-S(av) = 2.169 (2) A?, Rh-Cl(av) = 2.342 (2) A?, and Rh-S-Rh = 79.84 (7)°.
