Di-μ-sulfido-bis{[rac-1,2-bis(η5-4,5,6, 7-tetrahydroinden-1-yl)ethane]zirconium(IV)} toluene monosolvate
The title dimeric zirconium complex, [Zr3(C20H 24)2S2]·C7H8, was obtained from the reaction of (ebthi)Zr(η2-Me3Si-C2-SiMe3) [ebthi is rac-1,2-bis(η5-4,5,6,7-tetrahydroinden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each ZrIV atom is coordinated by the sterically hindered ebthi ligand and two μ-sulfide ligands in a strongly distorted tetrahedral geometry. The [ZrS]2 unit is almost planar (mean deviation from the best plane of the four atoms = 0.025Å). A -CH2-CH2- group in one ebthi ligand was disordered over two sites, with refined occupancy factors of 0.551(6) and 0.449(6). The asymmetric unit also contains a toluene solvent molecule.
(+)-Chlorido[(1,2,3,4-η;P 2′)-2′- diphenylphosphanyl-2-diphenylphosphoryl-1,1′-binaphthyl]rhodium(I) methanol monosolvate
In the title complex, [RhCl(C 44H 32OP 2)]·CH 3OH, the Rh I ion is coordinated by a naphthyl group of a partially oxidized 2,2′-bis-(diphenylphosphanyl)-1, 1′-binaphthyl (BINAP) ligand in a 4 mode, one P atom of the diphenylphosphanyl group and one Cl atom. The P=O group does not interact with the Rh I ion but accepts an O - H⋯O hydrogen bond from the methanol solvent molecule.
{2-[Bis(2,4-di-tert-butylphenoxy)-phosphanyloxy-κP]-3, 5-di-tert-butylphenyl-κC 1}[(1,2,5,6-η)-cycloocta-1,5-diene] rhodium(I) toluene monosolvate
The reaction of (η 3-allyl)[(1,2,5,6-η)-cycloocta-1,5- diene]rhodium(I) with tris-(2,4-di-tert-butylphenyl)phosphite in toluene produces the title compound, [Rh(C 42H 62O 3P)(C 8H 12)]·C 7H 8, by spontaneous metallation at one of the nonsubstituted phenyl ortho-C atoms of the phosphite molecule. The coordination geometry at the Rh I ion is distorted squareplanar. The toluene solvent molecule is disordered over two different orientations, with site-occupation factors of 0.810 (2) and 0.190 (2).
